------------------------------
Summary: Potential null deference in
CloneSnapshotProcedure#preCloneSnapshot()
Key: HBASE-15598
URL: https://issues.apache.org/jira/browse/HBASE-15598
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Assignee: Ted Yu
In CloneSnapshotProcedure#preCloneSnapshot():
{code}
ProcedureSyncWait.getMasterQuotaManager(env)
.checkNamespaceTableAndRegionQuota(getTableName(),
manifest.getRegionManifestsMap().size());
{code}
Here is related code in SnapshotManifest#getRegionManifestsMap() :
{code}
if (regionManifests == null || regionManifests.size() == 0) return null;
...
{code}
When there is no region manifest, null would be returned, resulting in NPE in
CloneSnapshotProcedure#preCloneSnapshot()
