HBase thrift2 TIOError

如果HBase thrift2报：“TIOError exception: Default TException”， 这个可能是因为操作的表不存在，不一定是网络或磁盘操作异常。 HBase Thrift2偷懒了，所有异常被统一成了TIOError和TIllegalArgument两个异常， 导致调用者无法区分，而且出错信息也没能很好的带过来，增加了定位工作量。 在HBase client中为如下一个继承关系： public class TableNotFoundException extends DoNotRetryIOException public class DoNotRetryIOException extends HBaseIOException public class HBaseIOException extends IOException HBase master相关日志： 2017-05-27 17:20:42,879 ERROR [thrift2-worker-7] client.AsyncProcess: Failed to get region location org.apache.hadoop.hbase.TableNotFoundException: ABCDE         at org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation.locateRegionInMeta(ConnectionManager.java:1285)         at org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation.locateRegion(ConnectionManager.java:1183)         at org.apache.hadoop.hbase.client.AsyncProcess.submit(AsyncProcess.java:422)         at org.apache.hadoop.hbase.client.AsyncProcess.submit(AsyncProcess.java:371)         at org.apache.hadoop.hbase.client.BufferedMutatorImpl.backgroundFlushCommits(BufferedMutatorImpl.java:245)         at org.apache.hadoop.hbase.client.BufferedMutatorImpl.flush(BufferedMutatorImpl.java:197)         at org.apache.hadoop.hbase.client.HTable.flushCommits(HTable.java:1461)         at org.apache.hadoop.hbase.client.HTable.put(HTable.java:1017)         at org.apache.hadoop.hbase.thrift2.ThriftHBaseServiceHandler.put(ThriftHBaseServiceHandler.java:243)         at sun.reflect.GeneratedMethodAccessor2.invoke(Unknown Source)
