Subject [jira] [Commented] (HBASE-18089) TestScannerHeartbeatMessages fails in branch-1
Date Fri, 16 Jun 2017 12:16:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16051822#comment-16051822
] 

Xiang Li commented on HBASE-18089:
----------------------------------

The logic of testImportanceOfHeartbeats(testHeartbeatBetweenRows()):
* Set client scanner lease period (timeout) to 1000 ms (see CLIENT_TIMEOUT)
* It scans 5 rows (see NUM_ROWS), and set the time to sleep between each row to 200 ms (see
DEFAULT_ROW_SLEEP_TIME).
* The call duration is like 1000+ ms (a little more than DEFAULT_ROW_SLEEP_TIME * NUM_ROWS
ms), while call time-out is 1000 ms (set by client scanner lease period), so it will time-out
if heartbeat is disabled.
* Result expected
** When heartbeat is enabled, no exception is expected
** When heartbeat is disabled, the following exception is expected
{code}
java.net.SocketTimeoutException: callTimeout=1000, callDuration=1016: Call to xxxx failed
on local exception: org.apache.hadoop.hbase.ipc.CallTimeoutException: Call id=34, waitTime=1013,
rpcTimetout=1000 row '' on table 'testScannerHeartbeatMessagesTable' at region=testScannerHeartbeatMessagesTable,,1497612784023.958b55cc0d2971377a027bdf1a1698fa.,
hostname=xxxx, seqNum=2
{code}
