Subject [jira] [Commented] (ACCUMULO-467) Allow the properties for AccumuloFileOutputFormat to be set in a mapreduce job
Date Wed, 12 Dec 2012 20:49:21 GMT


John Vines commented on ACCUMULO-467:

Minor quibble - AccumuloOutputFormat, set compression type, I don't like the hardcoded list
of supported options there as it seems like something which can be easily missed should we
add more compression types. Instead we should just have a javadoc reference to RFile or wherever
it is we maintain a list of supported options.

> Currently there is no way to set any of the configuration options for AccumuloFileOutputFormat
in a mapreduce job. Specifically the compression code, file block compression size, and index
block compression size to name a few.  Since AccumuloFileOutputFormat calls FileOperations.getInstance.openWriter()
 which takes both a Configuration and AccumuloConfiguration one could inside the openWriter
function check to see if the parameters are specified in the Configuration object and if not
take the default parameters from the AccumuloConfiguration object.
