    }
    LockedResource lockedResource = getLockResource(resourceType, resourceName);
    if (lockedResource != null) {
        String msg = resourceType.toString() + " '" + resourceName + "', shared lock count=" + lockedResource.getSharedLockCount();
        Procedure<?> proc = lockedResource.getExclusiveLockOwnerProcedure();
        if (proc != null) {
            msg += ", exclusively locked by procId=" + proc.getProcId();
        }

    }
}

Example 2 with LockedResourceType

use of org.apache.hadoop.hbase.procedure2.LockedResourceType in project hbase by apache.

    Procedure<?> exclusiveLockOwnerProcedure;
    int sharedLockCount;
    if (queue.hasExclusiveLock()) {
