-----------------------------------------
Summary: NPE in defragmentation / checkpoint
Key: IGNITE-20047
URL: https://issues.apache.org/jira/browse/IGNITE-20047
Project: Ignite
Issue Type: Bug
Reporter: Vladimir Steshin
NPE can occur in
{code:java}
/** {@inheritDoc} */
@Override public void updateEvictedPages(int delta) {
A.ensure(delta > 0, "param must be positive");
if (evictedPagesCounter() != null)
evictedPagesCounter().addAndGet(delta);
}
{code}
because evictedPagesCounter is already null. `clearCounters()` is invoked in
_markCheckpointEnd()_. But it is possible that the counter is being updated.
Probably, happens with the _DelayedDirtyPageStoreWrite_ /
_DelayedDirtyPageStoreWrite_
Found in the defragmentation process. But it seems to be a common problem. Logs
attached.
