[jira] [Created] (HDFS-16254) Cleanup protobuf on exit of hdfs_allowSnapshot

Gautham Banasandra created HDFS-16254:
-----------------------------------------

             Summary: Cleanup protobuf on exit of hdfs_allowSnapshot
                 Key: HDFS-16254
                 URL: https://issues.apache.org/jira/browse/HDFS-16254
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: libhdfs++, tools
    Affects Versions: 3.4.0
            Reporter: Gautham Banasandra
            Assignee: Gautham Banasandra


Need to move the call google::protobuf::ShutdownProtobufLibrary() to main method instead of [AllowSnapshot::HandlePath|https://github.com/apache/hadoop/blob/35a8d48872a13438d4c4199b6ef5b902105e2eb2/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfspp/tools/hdfs-allow-snapshot/hdfs-allow-snapshot.cc#L116-L117] since we want the clean-up tasks to run only when the program exits.
The current implementation doesn't cause any issues since AllowSnapshot::HandlePath is called only once.
