Subject [jira] [Updated] (HBASE-15593) Time limit of scanning should be offered by client
Date Tue, 05 Apr 2016 12:48:25 GMT

     [ https://issues.apache.org/jira/browse/HBASE-15593?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Phil Yang updated HBASE-15593:
------------------------------
    Description: In RSRpcServices.scan, we will set a time limit equaling to Math.min(scannerLeaseTimeoutPeriod,
rpcTimeout) / 2, and will response heartbeat message if we reach this limit. However, two
timeout settings (hbase.client.scanner.timeout.period and hbase.rpc.timeout) are read from
RS's configure, which may be different from client's. If client's setting is much less than
server's, there may still be timeout at client side.  (was: In RSRpcServices.scan, we will
set a time limit equaling to Math.min(scannerLeaseTimeoutPeriod, rpcTimeout) / 2, and will
response heartbeat message if we reach this limit. However, two timeout settings (hbase.client.scanner.timeout.period
and hbase.rpc.timeout) is read from RS's configure, which may be different from client's.
If client's setting is much less than server's, there may still be timeout at client side.)
