Subject [jira] [Updated] (HBASE-7289) Strip Writable from KeyValue
Date Tue, 11 Dec 2012 05:37:22 GMT

     [ https://issues.apache.org/jira/browse/HBASE-7289?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-7289:
-------------------------

    Release Note: 
Strips Writable from KeyValue.  Side effect has us protobuf'ing KeyValue when we put it into
a Result so this should SLOW HBase considerably until we address KeyValue serialization over
in HBASE-7233.

HBASE-7215 added MapReduce serializers for Result, Put, Delete, etc.  This issue adds a serializer
for KeyValue.  If using HFileOutputFormat, be sure to add the serializer to your configuration:
for example:

{code}
    Job job = new Job(conf, "YOUR_MAPREDUCE_JOB");
    job.getConfiguration().setStrings("io.serializations", conf.get("io.serializations"),
        MutationSerialization.class.getName(), ResultSerialization.class.getName(),
        KeyValueSerialization.class.getName());
{code}

  was:Strips Writable from KeyValue.  Side effect has us protobuf'ing KeyValue when we put
it into a Result so this should SLOW HBase considerably until we address KeyValue serialization
over in HBASE-7233

> Made new issue to strip Writable from KeyValue.  It used to be HBASE-7233 but I morphed
my own issue discussion of how to serialize KVs.
> This issue is about removing Writable from KV and making baseline protobufing work over
mapreduce and rpc.
