In 1.4.13, the warmed up region is not closed too. It's not the cause. https://github.com/apache/hbase/blob/rel/1.4.13/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java#L7163-L7164 I misunderstood your question. There are two points. The first is the leakage of open FDs during region moving(due to warmup), and the second is that HBase 2.4 opens much more FDs than HBase 1.4. In this PR, I fixed the first. The second is still in question. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
