----------------------------
Summary: Fix bug in synchronizing over ProcedureEvent
Key: HBASE-19319
URL: https://issues.apache.org/jira/browse/HBASE-19319
Project: HBase
Issue Type: Bug
Reporter: Appy
Assignee: Appy
Following synchronizes over local variable rather than the original
ProcedureEvent object. Clearly a bug since this code block won't follow
exclusion with many of the synchronized methods in ProcedureEvent class.
{code}
@Override
public void wakeEvents(final int count, final ProcedureEvent... events) {
final boolean traceEnabled = LOG.isTraceEnabled();
schedLock();
try {
int waitingCount = 0;
for (int i = 0; i < count; ++i) {
final ProcedureEvent event = events[i];
synchronized (event) {
if (!event.isReady()) {
{code}
