Sahil Takiar commented on IMPALA-7107:
--------------------------------------
[~jeszyb] IMPALA-8408 was fixed by IMPALA-6941, but all IIUC IMPALA-6941
doesn't actually add support for querying text files stored using DEFLATE.
IMPALA-6941 just fixes the query hang issue reported in IMPALA-8408 and adds a
plugin interface to the text scanners so that arbitrary compression codecs can
be supported. However, I don't actually see an implementation of the plugin
interface for DEFLATE files.

> Key: IMPALA-7107
> URL: https://issues.apache.org/jira/browse/IMPALA-7107
> Project: IMPALA
> Issue Type: Bug
> Components: Docs
> Affects Versions: Impala 2.12.0
> Reporter: Balazs Jeszenszky
> Assignee: Alex Rodoni
> Priority: Minor
> Fix For: Impala 3.2.0
>
>
> There are several points to clear up or improve across these pages:
> * I'd refer to the Hive documentation on how to set compression codecs
> instead of documenting Hive's behaviour for file formats Impala cannot write
> * Add 'Ingesting file formats Impala can't write' section to 'How Impala
> Works with Hadoop File Formats' page, link that central location from
> wherever applicable. Unify the recommendation on data loading (usage of LOAD
> DATA or hive or manual copy).
> * add a compatibility matrix for compressions and file formats, clear up
> compatibility on 'How Impala Works with Hadoop File Formats' (the page is
> inconsistent even within itself, e.g. bzip2).
> * Remove references to Impala versions <2.0
