-------------------------------------
Summary: Detect client server jar mismatch/incomatibility by
looking at the jar version stored in the MANIFEST file
Key: PHOENIX-1678
URL: https://issues.apache.org/jira/browse/PHOENIX-1678
Project: Phoenix
Issue Type: Bug
Reporter: Samarth Jain
Today, our way of detecting whether client and server jars are different is by
comparing the static member variable values in MetadataProtocol.java. The check
is hacky and could easily break once we start considering clusters upgraded to
snapshot and "sunk" RC jars. The current mechanism is also prone to bugs when
developers forget to change the member variable values even though they changed
the underlying metadata.
If the jar names could be written to a MANIFEST file, then we can have a
mechanism of detecting whether client and server jars belong to different
versions or if they are incompatible.
