> Custom serdes which used to work in HDP 1.1 is no longer working with HDP 1.3.
> The issue happens when the partition serde is not of settable type in HDP
> 1.3. The below exception happens via FetchOperator as well as MapOperator.
> Inside FetchOperator consider the following call:
> getRecordReader()->ObjectInspectorConverters. getConverter()
> The output object inspector is of settable type(because it is generated via
> ObjectInspectorConverters.getConvertedOI()) where as the input object
> inspector that gets passed as serde.getObjectorInspector() and is
> non-settable. Inside getConverter(), the (inputOI.equals(outputOI)) check
> fails and the switch statement tries to cast the non-settable object
> inspector to a settable object inspector.
> The stack trace as follows:
> 2013-08-28 17:57:25,307 ERROR CliDriver (SessionState.java:printError(432)) -
