Impala cannot start SIGBUS crash

Hi, after updateing my data nodes and kernel, and restarting the cluster Impala failed to start the Daemons. I tried to restart the impala daemon, but did not helped. Also tested on CDH 5.10 and CDH 5.11.1.

Tried to install different version of Java as well, downgrade, didnt helped either.

 

Running Centos 7 and CDH 5.11.1

 

Any suggestions how to avoid this error?

OS reinstall is my last option, but I do not want to clean up the whole cluster.

Re: Impala cannot start SIGBUS crash

Found out that it is related to this issue

https://issues.apache.org/jira/browse/DAEMON-363

 

So editing in CM the Impala Daemon properties:

Impala Daemon Environment Advanced Configuration Snippet (Safety Valve)

JAVA_TOOL_OPTIONS=-Xss2m

 

Fixed the problem.

Re: Impala cannot start SIGBUS crash

This is https://issues.apache.org/jira/browse/IMPALA-5578

 

I think you will probably also need to update "Impala Catalog Server Environment Advanced Configuration Snippet (Safety Valve)" before you restart the catalog daemon.

Re: Impala cannot start SIGBUS crash

Catalog did not failed but you are right, it is just a matter of time when my kernel will be updated on master, so it would probably crash also.

Re: Impala cannot start SIGBUS crash

@Tomas79i am ruining  CDH 5.10 in production it is nice and clean 

However when we performed a fresh install on other box we had this JRE issue .

fixed it with your post . Apprecaited it .

Re: Impala cannot start SIGBUS crash

@Tim Armstrong 

As suggested I bumped the JAVA_TOOL_OPTIONS=-Xss2m .

do you have any rational  behind for -Xss2m ? can we increase it more does it depends on any parameter like number of quries and hits to impala daemon .

Re: Impala cannot start SIGBUS crash

"-Xss1280k" seems to be sufficient. The default is 1024k I believe, and previously that was always sufficient in our testing.

 

The crash was caused by a change to the linux kernel that modified the memory layout around thread stacks. As a result with the default Java stack size, the JVM somehow ends up accessing invalid memory. Increasing the stack size mitigates this.t

Re: Impala cannot start SIGBUS crash

@Tim Armstrongon more question

Could you let me know the Kernel version that it would fail (Centos / RHEL )

Since it is only being tested in testing enviroment , what should be done to the production box ?

Re: Impala cannot start SIGBUS crash

I don't have a list of affected kernels, particularly since so many different kernel versions were patched. I know the problem was the initial fix for CVE-2017-1000364, so you could check to see if the kernel version has that in it.

 

I believe many Linux vendors are working on a fix for the fix, e.g.  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865549 so this advice may become incorrect once the problem is resolved.
