17+ # This file provides a variety of site-specific settings to control Drill
18+ # launch settings. These are settings required when launching the Drillbit
19+ # or sqlline processes using Java. Some settings are for both, some for one
20+ # or the other.
21+ #
22+ # Variables may be set in one of four places:
23+ #
24+ # Environment (per run)
25+ # drill-env.sh (this file, per site)
26+ # distrib-env.sh (per distribution)
27+ # drill-config.sh (Drill defaults)
28+ #
29+ # Properties "inherit" from items lower on the list, and may be "overridden" by items
30+ # higher on the list. In the environment, just set the variable:
31+ #
32+ # export FOO=value
33+ #
34+ # To support inheritance from the environment, you must set values as shown below:
35+ #
36+ # export FOO=${FOO:-"value"}
37+ #
38+ # or a more specialized form.
39+
40+ # Amount of heap memory for the Drillbit process. Values are those supported by
41+ # the Java -Xms option. The default is 4G.
42+
43+ export DRILL_HEAP=${DRILL_HEAP:- " 4G"
44+
45+ # Maximum amount of direct memory to allocate to the Drillbit in the format
46+ # supported by -XX:MaxDirectMemorySize. Default is 8G.
47+
48+ export DRILL_MAX_DIRECT_MEMORY=${DRILL_MAX_DIRECT_MEMORY:- " 8G"
49+
50+ # Value for the JVM -XX:MaxPermSize option for the Drillbit. Default is 512M.
51+
52+ # export DRILLBIT_MAX_PERM=${DRILLBIT_MAX_PERM:-"512M"}
53+
54+ # Native library path passed to Java. Note: use this form instead
55+ # of the old form of DRILLBIT_JAVA_OPTS="-Djava.library.path=<dir>"
56+ # The old form is not compatible with Drill-on-YARN.
57+
58+ # export DRILL_JAVA_LIB_PATH=
59+
60+ # Value for the code cache size for the Drillbit. Because the Drillbit generates
61+ # code, it benefits from a large cache. Default is 1G.
62+
63+ # export DRILLBIT_CODE_CACHE_SIZE=${DRILLBIT_CODE_CACHE_SIZE:-"1G"}
64+
65+ # Provide a customized host name for when the default mechanism is not accurate
66+
67+ # export DRILL_HOST_NAME=`hostname`
68+
69+ # Base name for Drill log files. Files are named ${DRILL_LOG_NAME}.out, etc.
70+
71+ # DRILL_LOG_NAME="drillbit"
72+
73+ # Location to place Drill logs. Set to $DRILL_HOME/log by default.
74+
75+ # export DRILL_LOG_DIR=${DRILL_LOG_DIR:-$DRILL_HOME/conf}
76+
77+ # Location to place the Drillbit pid file when running as a daemon using
78+ # drillbit.sh start.
79+ # Set to $DRILL_HOME by default.
80+
81+ # export DRILL_PID_DIR=${DRILL_PID_DIR:-$DRILL_HOME}
82+
83+ # Custom JVM arguments to pass to the both the Drillbit and sqlline. Typically
84+ # used to override system properties as shown below. Empty by default.
85+
86+ # export DRILL_JAVA_OPTS="$DRILL_JAVA_OPTS -Dproperty=value"
87+
88+ # As above, but only for the Drillbit. Empty by default.
89+
90+ # export DRILLBIT_JAVA_OPTS="$DRILLBIT_JAVA_OPTS -Dproperty=value"
91+
92+ # Process priority (niceness) for the Drillbit when running as a daemon.
93+ # Defaults to 0.
94+
95+ # export DRILL_NICENESS=${DRILL_NICENESS:-0}
96+
97+ # Custom class path for Drill. In general, you should put your custom libraries into
98+ # your site directory's jars subfolder ($DRILL_HOME/conf/jars by default, but can be
99+ # customized with DRILL_CONF_DIR or the --config argument. But, if you must reference
100+ # jar files in other locations, you can add them here. These jars are added to the
101+ # Drill classpath after all Drill-provided jars. Empty by default.
102+
103+ # custom="/your/path/here:/your/second/path"
104+ # if [ -z "$DRILL_CLASSPATH" ]; then
105+ # export DRILL_CLASSPATH=${DRILL_CLASSPATH:$custom}
106+ # else
107+ # export DRILL_CLASSPATH="$custom"
108+ # fi
109+
110+ # Extension classpath for things like HADOOP, HBase and so on. Set as above.
111+
112+ # EXTN_CLASSPATH=...
113+
114+ # Note that one environment variable can't be set here: DRILL_CONF_DIR.
115+ # That variable tells Drill the location of this file, so this file can't
116+ # set it. Instead, you can set it in the environment, or using the
117+ # --config option of drillbit.sh or sqlline.
118+
119+ # -----------------------------------------------------------------------------
120+ # The following are "advanced" options seldom used except when diagnosing
121+ # complex issues.
122+ #
123+ # The prefix class path appears before any Drill-provided classpath entries.
124+ # Use it to override Drill jars with specialized versions.
125+
126+ # export DRILL_CLASSPATH_PREFIX=...
127+
128+ # Enable garbage collection logging in the Drillbit. Logging goes to
129+ # $DRILL_LOG_DIR/drillbit.gc. A value of 1 enables logging, all other values
130+ # (including the default unset value) disables logging.
131+
132+ # export SERVER_LOG_GC=${SERVER_LOG_GC:-1}
133+
134+ # JVM options when running the sqlline Drill client. For example, adjust the
135+ # JVM heap memory here. These are used ONLY in non-embedded mode; these
136+ # are client-only settings. (The Drillbit settings are used when Drill
137+ # is embedded.)
138+
139+ # export SQLLINE_JAVA_OPTS="-XX:MaxPermSize=512M"
140+
141+ # Arguments passed to sqlline (the Drill shell) at all times: whether
142+ # Drill is embedded in Sqlline or not.
143+
144+ # export DRILL_SHELL_JAVA_OPTS="..."
145+
146+ # Location Drill should use for temporary files, such as downloaded dynamic UDFs jars.
147+ # Set to "/tmp" by default.
148+ #
149+ # export DRILL_TMP_DIR="..."
