------------------------------------
Summary: Possible Resource Leak in
org.apache.hadoop.hdfs.server.aliasmap#InMemoryAliasMap
Key: HDFS-16031
URL: https://issues.apache.org/jira/browse/HDFS-16031
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Narges Shadab
We notice a possible resource leak in
[getCompressedAliasMap|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/aliasmap/InMemoryAliasMap.java#L320].
If {{finish()}} at line 334 throws an IOException, then {{tOut, gzOut}} and
{{bOut}} remain open since the exception isn't caught locally, and there is no
way for any caller to close them.
I've submitted a pull request to fix it.
