Critical Description
romil.choksi reported that snapshot owner couldn't restore snapshot on hbase 1.1
We saw the following in master log:
2016-05-20 00:22:17,186 DEBUG [B.defaultRpcServer.handler=23,queue=2,port=20000] ipc.RpcServer: B.defaultRpcServer.handler=23,queue=2,port=20000: callId: 15 service: MasterService methodName: RestoreSnapshot size: 70 connection: x.y:56508 org.apache.hadoop.hbase.security.AccessDeniedException: Insufficient permissions for user 'hrt_1' (global, action=ADMIN) at org.apache.hadoop.hbase.security.access.AccessController.requireGlobalPermission(AccessController.java:536) at org.apache.hadoop.hbase.security.access.AccessController.requirePermission(AccessController.java:512) at org.apache.hadoop.hbase.security.access.AccessController.preRestoreSnapshot(AccessController.java:1327) at org.apache.hadoop.hbase.master.MasterCoprocessorHost$73.call(MasterCoprocessorHost.java:881) at org.apache.hadoop.hbase.master.MasterCoprocessorHost.execOperation(MasterCoprocessorHost.java:1146) at org.apache.hadoop.hbase.master.MasterCoprocessorHost.preRestoreSnapshot(MasterCoprocessorHost.java:877) at org.apache.hadoop.hbase.master.snapshot.SnapshotManager.restoreSnapshot(SnapshotManager.java:726)
After adding some debug information, it turned out that the (request) SnapshotDescription passed to the method doesn't have owner set.
This problem doesn't exist in master branch.
