Noémi Pap-Takács resolved IMPALA-12820.
---------------------------------------
Resolution: Fixed
> Current Impala docs still suggest that LZO compression is supported
> -------------------------------------------------------------------
>
> Key: IMPALA-12820
> URL: https://issues.apache.org/jira/browse/IMPALA-12820
> Project: IMPALA
> Issue Type: Bug
> Components: Docs
> Affects Versions: Impala 4.3.0, Impala 4.4.0, Impala 5.0.0, Impala 4.5.3
> Reporter: Laszlo Gaal
> Assignee: Noémi Pap-Takács
> Priority: Major
>
> LZO support was removed from the Impala development environment in
> IMPALA-9709, more than 3 years agot, effectively ending support for LZO
> compression.
> The Impala-lzo repo received the last commit at about the same time, for
> IMPALA-3741.
> Despite this, even the current Impala docs list LZO compression as supported
> in several locations:
> * The start of
> https://impala.apache.org/docs/build/plain-html/topics/impala_txtfile.html
> lists LZO as supported,
> *
> https://impala.apache.org/docs/build/plain-html/topics/impala_txtfile.html#lzo
> describes how to create them,
> * https://impala.apache.org/docs/build/plain-html/topics/impala_orc.html says
> that LZO compression is suuported for ORC files,
> * while
> https://impala.apache.org/docs/build/plain-html/topics/impala_orc.html states
> that LZO compression is not available for Parquet files.
> It would be worth reviewing Impala docs for LZO references and align the docs
> with current Impala functionality.
