> Missing null check of rpcServer.scheduler.executor causes NPE with invalid
> value of hbase.client.default.rpc.codec
> ------------------------------------------------------------------------------------------------------------------
>
> Key: HBASE-28452
> URL: https://issues.apache.org/jira/browse/HBASE-28452
> Project: HBase
> Issue Type: Bug
> Reporter: ConfX
> Priority: Major
> Labels: pull-request-available
>
> 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
> {code:java}
> try (AbstractRpcClient<?> client =
> createRpcClientRTEDuringConnectionSetup(clientConf))
> { rpcServer.start(); . . . }
> {code}
>
> When finally block is executed which contains
> {code:java}
> finally
> { rpcServer.stop(); }
> {code}
>
> 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()`
>
> {code:java}
> java.lang.NullPointerException
> at org.apache.hadoop.hbase.ipc.FifoRpcScheduler.stop(FifoRpcScheduler.java:71)
> at org.apache.hadoop.hbase.ipc.SimpleRpcServer.stop(SimpleRpcServer.java:441)
> at
> org.apache.hadoop.hbase.ipc.AbstractTestIPC.testRTEDuringConnectionSetup(AbstractTestIPC.java:194){code}
