-----------------------------
Summary: Fix waitForMaximumCurrentTasks logic in AsyncProcess
Key: HBASE-15922
URL: https://issues.apache.org/jira/browse/HBASE-15922
Project: HBase
Issue Type: Bug
Reporter: Yu Li
In current implementation of AsyncProcess#waitForMaximumCurrentTasks, we have
below codes:
{code}
while ((currentInProgress = this.tasksInProgress.get()) > max) {
...
try {
synchronized (this.tasksInProgress) {
if (tasksInProgress.get() != oldInProgress) break;
this.tasksInProgress.wait(100);
}
} catch (InterruptedException e) {
throw new InterruptedIOException("#" + id + ", interrupted." +
" currentNumberOfTask=" + currentInProgress);
}
}
{code}
Which will cause end of while loop if there's any task done inside one loop
making {{taskInProgress.get()}} no longer equals to {{oldInProgress}}
This is a regression issue caused by HBASE-11403 and only exists in
branch-1/master branch, we could easily see the difference comparing to latest
0.98 code.
