------------------------------------
Summary: The method isChildReadLock in class
ZKInterProcessLockBase is wrong
Key: HBASE-11342
URL: https://issues.apache.org/jira/browse/HBASE-11342
Project: HBase
Issue Type: Bug
Components: Zookeeper
Affects Versions: 0.98.3, 0.99.0
Reporter: Qianxi Zhang
Assignee: Qianxi Zhang
Priority: Minor
The method isChildReadLock in class ZKInterProcessLockBase may be wrong, which
determines whether the lock is readLock or not. So we should compare the node
name with READ_LOCK_CHILD_NODE_PREFIX rather than WRITE_LOCK_CHILD_NODE_PREFIX.
Since there is no other method to invoke the method "isChildReadLock" now, we
have not encountered an error.
{code}
protected static boolean isChildReadLock(String child) {
int idx = child.lastIndexOf(ZKUtil.ZNODE_PATH_SEPARATOR);
String suffix = child.substring(idx + 1);
return suffix.startsWith(WRITE_LOCK_CHILD_NODE_PREFIX);
}
{code}
