> Inadequate information for handling catch clauses
> -------------------------------------------------
>
> Key: HDFS-13321
> URL: https://issues.apache.org/jira/browse/HDFS-13321
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode
> Affects Versions: 3.0.0
> Reporter: Zhenhao Li
> Priority: Major
> Labels: easyfix
>
> Their are some situations that different exception types are caught, but the
> handling of those exceptions can not show the differences of those types.
> Here are the code snippets we found which have this problem:
> *hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/BPServiceActor.java*
> [https://github.com/apache/hadoop/blob/bec79ca2495abdc347d64628151c90f5ce777046/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/BPServiceActor.java]
> At Line *233* and Line *235.* We can see that two exception types are caught,
> but the logging statements here can not show the exception type at all.
> Also there are comments for these two catch clauses respectively, one is
> "{color:#707070}// namenode is busy{color}", the other one is
> "{color:#707070}// namenode is not available",{color:#333333} but the log
> messages are too generic, can not show the "busy" or "not available" of
> namenode.{color}{color}
> It may cause confusions to the person who is reading the log, the person can
> not know what exception happened here and can not distinguish logs generated
> by these two statements.
> Maybe adding stack trace information to these two logging statements and
> change the log message to handle specific situations is a simple way to
> improve it.
