Subject [jira] [Commented] (DRILL-1871) JSON reader cannot read compressed files
Date Thu, 18 Dec 2014 23:05:13 GMT

    [ https://issues.apache.org/jira/browse/DRILL-1871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14252492#comment-14252492

Jason Altekruse commented on DRILL-1871:
----------------------------------------

Just a note, this currently relies on the default list of available decompressors from Hadoop.
This does not seems to currently include support to decompress .zip files, may want to see
if this can be enabled.
