> Pre-4.15 client cannot connect to 4.15+ server after SYSTEM.CATALOG region
> has split
> ------------------------------------------------------------------------------------
>
> Key: PHOENIX-5940
> URL: https://issues.apache.org/jira/browse/PHOENIX-5940
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.14.3
> Reporter: Chinmay Kulkarni
> Assignee: Xinyi Yan
> Priority: Blocker
> Fix For: 4.16.0
>
>
> Steps to repro:
> # Start the server with 4.15 or 4.16-SNAPSHOT (head of 4.x) with the default
> setting for splitting SYSTEM.CATALOG i.e.
> _phoenix.system.catalog.splittable=true_
> # Connect with a 4.15+ client and create enough tables/views/indices to
> cause the SYSTEM.CATALOG region to split (you may want to set the following
> server-side configs for a quicker repro:
> ## _hbase.hregion.memstore.flush.size=1048576_ i.e. 1MB (to flush memstores
> quicker),
> ## _hbase.hregion.max.filesize=2097152_ i.e. 2MB (so we don've have to load
> too much data to cause a region split),
> ## _hbase.zookeeper.property.maxClientCnxns=-1_ (If we don’t set this, the
> default limit is easily hit when creating hundreds of views),
> ## _hbase.table.sanity.checks=false_ (otherwise HBase complains that the
> HRegion max file size config is too small).
> # With these configs, I've found that creating ~4000 views is sufficient to
> cause the SYSTEM.CATALOG region to split.
> # Now connect with any pre-4.15 client like 4.14.3. Getting a connection
> will fail with the following stack trace:
> {noformat}

> The reason why this happens is that in a pre-4.15 client, inside
> CQSI.checkClientServerCompatibility, the getVersion method is invoked on
> MetaDataEndpointImpl over *all SYSTEM.CATALOG regions* (we pass in null for
> startKey and endKey), see
> [this|https://github.com/apache/phoenix/blob/e2993552dc88cb7fc59fc0dfdaa2876ac260886c/phoenix-core/src/main/java/org/apache/phoenix/query/ConnectionQueryServicesImpl.java#L1350].
> Inside MetaDataEndpointImpl#getVersion, we [call
> doGetTable|https://github.com/apache/phoenix/blob/77c6cb32fce04b912b7c502dc170d86af8293fe6/phoenix-core/src/main/java/org/apache/phoenix/coprocessor/MetaDataEndpointImpl.java#L3224]
> Now, if SYSTEM.CATALOG has split, this call will also be invoked on a region
> that does not contain the header row for SYSTEM.CATALOG causing it to fail in
> MetaDataEndpointImpl#doGetTable
> [here|https://github.com/apache/phoenix/blob/77c6cb32fce04b912b7c502dc170d86af8293fe6/phoenix-core/src/main/java/org/apache/phoenix/coprocessor/MetaDataEndpointImpl.java#L2928-L2933].
> This is avoided in 4.15+ clients since we have restricted the getVersion
> invocation to the region containing the header row for SYSTEM.CATALOG (see
> [this|https://github.com/apache/phoenix/blob/77c6cb32fce04b912b7c502dc170d86af8293fe6/phoenix-core/src/main/java/org/apache/phoenix/query/ConnectionQueryServicesImpl.java#L1517]).
> We need to add a special condition to consider pre-4.15 clients before
> propagating the error back to clients inside MetaDataEndpointImpl.
