Hi,
I could see java pointer error in drill logs as beow
*** Error in
`/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64/jre/bin/java':
free(): invalid pointer: 0x00007f5030000088 ***

What could be possible reasons for the error - Is it caused by Drill or its
the java issue ?

Appreciate the inputs !

Thanks,
Divya

Is there a stack trace? Does the Drillbit crash, because that might have generated a log as well (hs_error_.... ) ?

Hi ,
Yes, the Drill bit node goes down and it has generated the java core file .
Have pasted the stacktrace of the java core file here ->

Here is the drillbit.log output -> https://pastebin.com/X44guqiM

It looks like some authentication failure. I'm assuming it is not frequent, so it might not be a Drill issue. 

I also noticed that the original post showed the java executable as part of a JRE. For Drill, you need to use a JDK, because a JRE will not have compilation capabilities.

Can you switch to starting your Drillbits using a JDK instead and see if that resolves it?

I found the root cause of the issue .
Its the user's password got expired hence the error.
