Subject [jira] [Commented] (HBASE-5322) RetriesExhaustedException: Trying to contact region server
Date Thu, 23 Aug 2012 05:11:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13440060#comment-13440060

Karthik Pandian commented on HBASE-5322:

@Ian Varley,
I don't have the entire stack trace now as I have managed to split the data into multiple
tables but I am pretty sure that scanner hangs and may rise a time out exception for large
tables (>20GB). Even I faced the same issue for Hbase-MR Jobs.
Sample error log for scanner time out in MR job,
java.io.IOException: org.apache.hadoop.hbase.client.ScannerTimeoutException: 63882ms passed
since the last invocation, timeout is

Even I tried to increase the timeout as well and I am caching only 300 rows for each scan.

> I have a hbase table which holds data for more than 10GB. Now I used the same client
scanner to scan which fails and reports,
> "Could not seek StoreFileScanner[HFileScanner for reader reader=hdfs".
> This issue occurs only for the table which holds huge data and not for tables holding
small data.
