Work Description: ayushtkn commented on PR #4249:
URL: https://github.com/apache/hive/pull/4249#issuecomment-1516059041
> The "out of sequence response" error occurs when two threads use the same
HiveMetaStoreClient instance.
It seems that the metastore client socket is reading the RPC response from a
different call, hence the out-of-sequence exception.
That sounds like a bug in the **RPC** layer, two threads sharing HMSClient
instance is same as two threads sharing FileSystem instances and invoking calls
to server.
The RPC layer should isolate those calls and shouldn't goof up. Every RPC
AFAIK should be associated with RPC callId and ClientId, Atleast the Hadoop RPC
layer does pass that.
This should be easily reproducible then in a normal multithreading execution?
