----------------------------------------

             Summary: har file system throws ArrayIndexOutOfBoundsException
                 Key: HADOOP-14950
                 URL: https://issues.apache.org/jira/browse/HADOOP-14950
             Project: Hadoop Common
          Issue Type: Bug
         Environment: CDH 5.9.2
            Reporter: Wei-Chiu Chuang
            Assignee: Wei-Chiu Chuang


When listing a har file system file, it throws an AIOOBE like the following:

{noformat}
$ hdfs dfs -ls har:///abc.har
-ls: Fatal internal error
java.lang.ArrayIndexOutOfBoundsException: 1

at org.apache.hadoop.fs.FsShell.main(FsShell.java:372)
{noformat}

Checking the code, it looks like the _index file in the har is mal-formed. It expects two string separately by a space in each line, and this AIOOBE is possible if the second string does not exist.

File this jira to improve the error handling of such case.
