[jira] Updated: (HIVE-270) Add a lazy-deserialized SerDe for space and cpu efficient serialization of rows with primitive types
[ https://issues.apache.org/jira/browse/HIVE-270?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Zheng Shao updated HIVE-270: Attachment: HIVE-270.3.patch Added the code to parse byte, short, int, long without doing UTF-8 decoding. Added test cases (all passed). Does not include the fix to existing testcase output. The only change is the name of the SerDe and that part can be automatically generated by "ant test -Doverwrite=true". > Add a lazy-deserialized SerDe for space and cpu efficient serialization of > rows with primitive types > > > Key: HIVE-270 > URL: https://issues.apache.org/jira/browse/HIVE-270 > Project: Hadoop Hive > Issue Type: New Feature > Components: Serializers/Deserializers >Reporter: Zheng Shao >Assignee: Zheng Shao > Attachments: HIVE-270.1.patch, HIVE-270.3.patch > > > We want to add a lazy-deserialized SerDe for space and cpu efficient > serialization of rows with primitive types. > This SerDe will share the same format as > MetadataTypedColumnsetSerDe/TCTLSeparatedProtocol to be backward compatible. > This SerDe will be used to replace the default table SerDe, and the SerDe > used to communicate with user scripts. > For simplicity, we don't plan to support nested structure with this SerDe. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.

RE: Implementing Timestamp (HIVE-192)
Will add them once they get the apache accounts and can actually commit code... I guess at that point they can add themselves in as well :) Ashish -Original Message- From: Jeff Hammerbacher [mailto:ham...@cloudera.com] Sent: Tuesday, February 10, 2009 3:08 AM To: hive-dev@hadoop.apache.org Subject: Re: Implementing Timestamp (HIVE-192) We should add Namit and Prasad to that page...

Re: Implementing Timestamp (HIVE-192)
The ticket hasn't been commented on so I'm going to assume that nobody is working on it, so please do go ahead and have a go at it. As for who you should talk to, someone on this list should probably jump in, but the committers are a good start: http://hadoop.apache.org/hive/credits.html There's also an IRC channel where some of them pop in now and again: ##hive at irc.freenode.net I haven't worked with serde much so can't give any pointers where to start. /Johan Shyam Sarkar wrote: > Hello, > > I like to go deeper into Hive code (starting from parser all the way to file > system) by implementing a small feature first.

[jira] Updated: (HIVE-272) Eliminate @Override directives for classes in Eclipse 3.4.1
[ https://issues.apache.org/jira/browse/HIVE-272?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Raghotham Murthy updated HIVE-272: -- Resolution: Invalid Status: Resolved (was: Patch Available) There seems to be quite a bit of confusion about changing the meaning of @Override between 1.5 and 1.6. See: http://blogs.sun.com/ahe/?entry=override But, the conclusion is that its ok in 1.6 to specify @Override to methods inherited from interfaces. So, this jira can be closed. We do need to make a change to our eclipse-templates to make sure that eclipse has java compiler compliance level set to 1.6. > Eliminate @Override directives for classes in Eclipse 3.4.1 > --- > > Key: HIVE-272 > URL: https://issues.apache.org/jira/browse/HIVE-272 > Project: Hadoop Hive > Issue Type: Improvement > Components: Build Infrastructure >Affects Versions: 0.2.0 > Environment: Eclipse 3.4.1 >Reporter: Shyam Sundar Sarkar >Assignee: Raghotham Murthy > Fix For: 0.3.0 > > Attachments: hive-272.1.patch > > > Eclipse Versions prior to 3.4.1 actually add @Override to classes which > implement interfaces.
