Summary: Possible Resource Leak in
HeterogeneousRegionCountCostFunction
Key: HBASE-25626
URL: https://issues.apache.org/jira/browse/HBASE-25626
Project: HBase
Issue Type: Bug
Reporter: Narges Shadab
We noticed a possible resource leak
[here|https://github.com/apache/hbase/blob/b522d2a33e31fbe70c341ea7068428ada8d51bc0/hbase-server/src/main/java/org/apache/hadoop/hbase/master/balancer/HeterogeneousRegionCountCostFunction.java#L225].
close() is called on {{reader}} at line 228 but if an I/O error occurs at line
225, {{reader}} remains open since the exception isn't caught locally.
I'll submit a pull request to fix it.
