[jira] [Created] (HBASE-19681) Online snapshot creation failing
with missing store file
Anirban Roy created HBASE-19681:
-----------------------------------
Summary: Online snapshot creation failing with missing store file
Key: HBASE-19681
URL: https://issues.apache.org/jira/browse/HBASE-19681
Project: HBase
Issue Type: Bug
Components: backup&restore, snapshots
Affects Versions: 1.3.0
Environment: Hadoop - 2.7.3
HBase 1.3.0
OS - GNU/Linux x86_64
Cluster - Amazon Elastic Mapreduce
Reporter: Anirban Roy
We are facing problem creating online snapshot of our HBase table. The table contains 20TB data and receiving ~10000 writes per second. The snapshot creating failing intermittently with error that some hfile missing, see the detailed output below. Once we locate the region server hosting the region and restart the region server, snapshot creation succeeds. It seems the missing hfile removed due to minor compaction, but region server still holds the pointer to the file.

Here is some help for this command:
Take a snapshot of specified table. Examples:
hbase> snapshot 'sourceTable', 'snapshotName'
hbase> snapshot 'namespace:sourceTable', 'snapshotName', {SKIP_FLUSH => true}
