> LLAP cache always misses with non-vectorized serde readers such as OpenCSV
> --------------------------------------------------------------------------
>
> Key: HIVE-22583
> URL: https://issues.apache.org/jira/browse/HIVE-22583
> Project: Hive
> Issue Type: Bug
> Components: llap
> Reporter: Ádám Szita
> Assignee: Ádám Szita
> Priority: Major
> Attachments: HIVE-22583.0.patch, HIVE-22583.1.patch
>
>
> Although after the first read LLAP cache stores data of tables that are not
> using the LazySimple serde, the stored data is then never used in the future
> subsequent queries, causing a full cache miss and re-read each time.
> Problem is rooted in SerdeEncodedDataReader#cacheFileData is not taking care
> of creating an entry for the root/struct column of the table. The only cases
> this is taken care of are when a vectorized reader is used _(e.g.
> LazySimpleSerde's LazySimpleDeserializeRead)_, where
> SerdeEncodedDataReader#processAsyncCacheData takes care of this.
> This can be reproduced by either using a custom serde, like OpenCSV or using
> LazySimpleSerde, but turning off _hive.llap.io.encode.vector.serde.enabled_.
