[jira] [Created] (IMPALA-7172) Statestore should verify that all
subscribers are running the same version of Impala
Mostafa Mokhtar created IMPALA-7172:
---------------------------------------
Summary: Statestore should verify that all subscribers are running the same version of Impala
Key: IMPALA-7172
URL: https://issues.apache.org/jira/browse/IMPALA-7172
Project: IMPALA
Issue Type: New Feature
Components: Distributed Exec
Affects Versions: Impala 2.13.0
Reporter: Mostafa Mokhtar
While running a metadata test which uses sync_ddl=1, tests appeared to hang indefinitely.
Turns out one of the Impala daemons was running an older build which caused statestore topic updates to continuously fail.
Ideally the SS should track the version across subscribers and black list the ones that don't match the SS and CS version.
