ConfX created HBASE-27994:
-----------------------------
Summary: Missing null check of rpcServer.scheduler.executor
causes NPE with invalid value of hbase.client.default.rpc.codec
Key: HBASE-27994
URL: https://issues.apache.org/jira/browse/HBASE-27994
Project: HBase
Issue Type: Bug
Reporter: ConfX
When {{hbase.client.default.rpc.codec}} is set to
{{org.apache.hadoop.hbase.regionserver.wal.SecureWALCellCodec}} the method
{{createRpcClientRTEDuringConnectionSetup}} gives a NoSuchMethodException for
the provided default codec value.
Since there was an exception, the code inside try block is not executed which
contained the below code line
{noformat}
try (AbstractRpcClient<?> client =
createRpcClientRTEDuringConnectionSetup(clientConf)) {
rpcServer.start();
. . .
}{noformat}
When finally block is executed which contains
{noformat}
finally {
rpcServer.stop();
}{noformat}
The method {{rpcServer.stop()}} eventually makes call to
{{{}executor.shutdown(){}}}. A null pointer exception is returned as
{{rpcServer.scheduler.executor}} was never instantiated, which happens inside
{{rpcServer.start()}}
{noformat}
