ATTACHMENT ID: 12672889
> Use base-64 encoding instead of custom encoding for serialized objects
> ----------------------------------------------------------------------
>
> Key: HIVE-8347
> URL: https://issues.apache.org/jira/browse/HIVE-8347
> Project: Hive
> Issue Type: Improvement
> Components: HCatalog
> Affects Versions: 0.13.1
> Reporter: Mariappan Asokan
> Attachments: HIVE-8347.patch
>
>
> Serialized objects that are shipped via Hadoop {{Configuration}} are encoded
> using custom encoding (see {{HCatUtil.encodeBytes()}} and its complement
> {{HCatUtil.decodeBytes()}}) which has 100% overhead. In other words, each
> byte in the serialized object becomes 2 bytes after encoding. Perhaps, this
> might be one of the reasons for the problem reported in HCATALOG-453. The
> patch for HCATALOG-453 compressed serialized {{InputJobInfo}} objects to
> solve the problem.
> By using Base64 encoding, the overhead will be reduced to about 33%. This
> will alleviate the problem for all serialized objects.
