Allan Yang updated HBASE-18233:
-------------------------------
Comment: was deleted
(was: Hi, [~stack], tryLock() with no parameter means do not wait for this
lock. please see the java docs:
{code}
/**
* Acquires the lock only if it is free at the time of invocation.
*
* <p>Acquires the lock if it is available and returns immediately
* with the value {@code true}.
* If the lock is not available then this method will return
* immediately with the value {@code false}.
*
* <p>A typical usage idiom for this method would be:
* <pre> {@code
* Lock lock = ...;
* if (lock.tryLock()) {
* try {
* // manipulate protected state
* } finally {
* lock.unlock();
* }
* } else {
* // perform alternative actions
* }}</pre>
*
* This usage ensures that the lock is unlocked if it was acquired, and
* doesn't try to unlock if the lock was not acquired.
*
* @return {@code true} if the lock was acquired and
* {@code false} otherwise
*/
boolean tryLock();

> We shouldn't wait for readlock in doMiniBatchMutation in case of deadlock
