Sushanth Sowmyan commented on HIVE-8347: ---------------------------------------- None, this looks good to me. There is no place where we store the result of a serialized string, it's only used for on the wire/on the jobconf. Looks good to me, +1. > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
