------------------------------
Summary: LLAP: Fail to package LLAP if the Xmx computed is 0
Key: HIVE-20416
URL: https://issues.apache.org/jira/browse/HIVE-20416
Project: Hive
Issue Type: Bug
Components: llap
Reporter: Gopal V
{code}
if (options.getXmx() != -1) {
// Needs more explanation here
// Xmx is not the max heap value in JDK8. You need to subtract 50% of
the survivor fraction
// from this, to get actual usable memory before it goes into GC
xmx = options.getXmx();
long xmxMb = (xmx / (1024L * 1024L));
conf.setLong(ConfVars.LLAP_DAEMON_MEMORY_PER_INSTANCE_MB.varname,
xmxMb);
propsDirectOptions.setProperty(ConfVars.LLAP_DAEMON_MEMORY_PER_INSTANCE_MB.varname,
String.valueOf(xmxMb));
{code}
needs a check for the value being so low that start-up (or all queries) will
fail.
