Subject [jira] [Commented] (HDFS-8885) ByteRangeInputStream used in webhdfs does not override available()
Date Wed, 26 Aug 2015 10:00:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14712866#comment-14712866

Shradha Revankar commented on HDFS-8885:

Hi [~cnauroth],
Thank you for reviewing this, {{getInputStream()}} is called in the constructor of {{ByteRangeInputStream}},
so 1 and 2 should not occur. Do you still think this should be called again in {{avaliable}}?
3. Agree, will add this check.
4.I will add testcases, sorry about not doing it in the first patch.

> ByteRangeInputStream has to override the method {{available()}} , the super class implementation
returns 0. Clients using the method {{available()}} to rely on available bytes information
will end up with errors during reads if WebhdfsFileSystem is used.
