Jianwei Cui commented on HBASE-15433: ------------------------------------- Thanks for your comment [~ashish singhi], I made a patch to fix this case and will upload after test passed:) > SnapshotManager#restoreSnapshot not update table and region count quota > correctly when encountering exception > ------------------------------------------------------------------------------------------------------------- > > Key: HBASE-15433 > URL: https://issues.apache.org/jira/browse/HBASE-15433 > Project: HBase > Issue Type: Bug > Components: snapshots > Affects Versions: 2.0.0 > Reporter: Jianwei Cui > > In SnapshotManager#restoreSnapshot, the table and region quota will be > checked and updated as: > {code} > try { > // Table already exist. Check and update the region quota for this > table namespace > checkAndUpdateNamespaceRegionQuota(manifest, tableName); > restoreSnapshot(snapshot, snapshotTableDesc); > } catch (IOException e) { > > this.master.getMasterQuotaManager().removeTableFromNamespaceQuota(tableName); > LOG.error("Exception occurred while restoring the snapshot " + > snapshot.getName() > + " as table " + tableName.getNameAsString(), e); > throw e; > } > {code} > The 'checkAndUpdateNamespaceRegionQuota' will fail if regions in the snapshot > make the region count quota exceeded, then, the table will be removed in the > 'catch' block. This will make the current table count and region count > decrease, following table creation or region split will succeed even if the > actual quota is exceeded. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
