hello cloudera community,

we are having problem in impala after enabling kerberos on cdp cluster

only the Impala StateStore role is started healthy, the other roles are in bad status

checking the log of the Impala Catalog Server role, the following appears:

-------------

. Impalad exiting.
Wrote minidump to /var/log/impala-minidumps/catalogd/7ae4848b-cd34-4d4c-96cfeaa3-bd4a584f.dmp

Hi @yagoaparecidoti

The mini dump created shows that role/process is failing due to memory error.

You may need to analyse this dmp file to check why the role/process is failing.

hi @jAnshula

thanks for message

but at the time of the error, it was related to a configuration in cloudera manager regarding supported encryption types 😁
