> problem: In S3a environment, when quiried the data which has dictionary files,
> Dictionary file cannot be read in S3a with
> CarbonDictionaryDecoder.doConsume() codeGen even though file is present.
>
> cause: CarbonDictionaryDecoder.doConsume() codeGen doesn't set hadoop conf in
> thread local variable, only doExecute() sets it.
> Hence, when getDictionaryWrapper() called from doConsume() codeGen,
> AbstractDictionaryCache.getDictionaryMetaCarbonFile() returns false for
> fileExists() operation.
>
> solution:
> In CarbonDictionaryDecoder.doConsume() codeGen, set hadoop conf in thread
> local variable
