Zhihong Yu commented on HBASE-5153: ----------------------------------- For the trunk patch: {code} + * @param actions + * The collection of actions. + * @param tableName + * Name of the hbase table {code} The explanation should be on the same line as parameter name. {code} + * Check the connection. If it has been closed, we should recreate the + * Connection. See HBASE-5153. + * + * @param ioe + * The IOE throwed by the HConnection methods. {code} Connection on second line above should start with lower case 'c'. throwed should be thrown. {code} + throw new RetriesExhaustedException( + "Retry to recreate connection in HTable, but failed."); {code} Please include the value of tries in the exception message. Good work. > HConnection re-creation in HTable after HConnection abort > --------------------------------------------------------- > > Key: HBASE-5153 > URL: https://issues.apache.org/jira/browse/HBASE-5153 > Project: HBase > Issue Type: Bug > Components: client > Affects Versions: 0.90.4 > Reporter: Jieshan Bean > Assignee: Jieshan Bean > Fix For: 0.90.6 > > Attachments: 5153-trunk.txt, HBASE-5153-V2.patch, > HBASE-5153-V3.patch, HBASE-5153-V4-90.patch, HBASE-5153-trunk.patch, > HBASE-5153.patch > > > HBASE-4893 is related to this issue. In that issue, we know, if multi-threads > share a same connection, once this connection got abort in one thread, the > other threads will got a > "HConnectionManager$HConnectionImplementation@18fb1f7 closed" exception. > It solve the problem of "stale connection can't removed". But the orignal > HTable instance cann't be continue to use. The connection in HTable should be > recreated. > Actually, there's two aproach to solve this: > 1. In user code, once catch an IOE, close connection and re-create HTable > instance. We can use this as a workaround. > 2. In HBase Client side, catch this exception, and re-create connection. -- This message is automatically generated by JIRA.
