> Similar to [HBASE-9256 | https://issues.apache.org/jira/browse/HBASE-9256], SecureClient#setupIOStreams
should also catch up all Exception. In our production environment, an OutOfMemoryError is
thrown in SecureClient#setupIOStreams, leaving an unclosed SecureConnection with its inputStream/outputStream
still null. Therefore, following calls will be attached to this connection and will encounter
NPE in HBaseClient#sendParam:
> {code}
> java.lang.NullPointerException
> at org.apache.hadoop.hbase.ipc.HBaseClient$Connection.sendParam(HBaseClient.java:619)
> at org.apache.hadoop.hbase.ipc.HBaseClient.call(HBaseClient.java:977)
> at org.apache.hadoop.hbase.ipc.SecureRpcEngine$Invoker.invoke(SecureRpcEngine.java:107)
> at $Proxy21.replicateLogEntries(Unknown Source)
> at org.apache.hadoop.hbase.replication.regionserver.ReplicationSource.shipEdits(ReplicationSource.java:772)
> at org.apache.hadoop.hbase.replication.regionserver.ReplicationSource.run(ReplicationSource.java:451)
> {code}
> We'd fix this in 0.94.
