Zheng Shao updated HADOOP-10906:
--------------------------------
Summary: getContentSummary() for HarFileSystem throws
IllegalArgumentException (was: getConetentSummary() for HarFileSystem throws
IllegalArgumentException)
> getContentSummary() for HarFileSystem throws IllegalArgumentException
> ---------------------------------------------------------------------

> Key: HADOOP-10906
> URL: https://issues.apache.org/jira/browse/HADOOP-10906
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Paul Yang
>
> As HarFileSystem does not implement getContentSummary(), the implementation
> from FilterFileSystem is inherited by default. However,
> FilterFileSystem.getContentSummary() does not work for the HarFileSystem
> because the method attempts to use HarFileSystem's underlying FS to call
> getContentSummary(). In the case where the the underlying filesystem is HDFS,
> an exception similar to the following is thrown:
> {code}
> java.lang.IllegalArgumentException: Wrong FS:
> har://hdfs-example.com:9000/tmp/data.har, expected: hdfs://example.com:9000
> at org.apache.hadoop.fs.FileSystem.checkPath(FileSystem.java:352)
> at
> org.apache.hadoop.hdfs.DistributedFileSystem.checkPath(DistributedFileSystem.java:99)
> at
> org.apache.hadoop.hdfs.DistributedFileSystem.getPathName(DistributedFileSystem.java:155)
> at
> org.apache.hadoop.hdfs.DistributedFileSystem.getContentSummary(DistributedFileSystem.java:232)
> at
> org.apache.hadoop.fs.FilterFileSystem.getContentSummary(FilterFileSystem.java:287)
> at
> org.apache.hadoop.fs.FilterFileSystem.getContentSummary(FilterFileSystem.java:287)
> {code}
> One solution is to implement HarFileSystem.getContentSummary() using code
> similar to FileSystem.getContentSummary().
