Subject [jira] [Commented] (ACCUMULO-1854) AccumuloInputFormat can be less strict about contents of Configuration
Date Mon, 25 Nov 2013 18:44:37 GMT


Josh Elser commented on ACCUMULO-1854:

Felt the need to update the title and description to better match what was actually done and
be a little less misleading.

>             Project: Accumulo
>          Issue Type: Bug
>    Affects Versions: 1.4.4, 1.5.0
>            Reporter: Josh Elser
>            Assignee: Josh Elser
>             Fix For: 1.4.5, 1.5.1, 1.6.0
> The AccumuloInputFormat required that the same exact Configuration object which was provided
to its static configuration methods is also provided to its getSplits() and createRecordReader()
> In practice, some tools, like MultipleInputs or Pig, don't guarantee that the same Configuration
object is provided to getSplits() and createRecordReader(). This tends to be a common method
of interaction to ensure that multiple InputFormats don't collide with one another in the
same Configuration object (e.g. FileInputFormat). By serialization the necessary information
from the Configuration regarding how to query Accumulo into the InputSplit AccumuloInputFormat
creates, we can alleviate this requirement and make client interaction a little more standard.
