Hi Vinay,

Thanks for the response.

I have NOT enabled any checkpointing.

Files are rolling out correctly for every 2mb, but the files are remaining as below:

-rw-r--r--   3 2097424 2017-08-06 21:10 /xxxx/xxxx/xxxx/Test/part-0-0.pending
-rw-r--r--   3 1431430 2017-08-06 21:12 /xxxx/xxxx/xxxx/Test/part-0-1.pending

Hi Raja,

Have you enabled checkpointing?
The files will be rolled to complete state when the batch size is reached (in your case 2
MB) or when the bucket is inactive for a certain amount of time.

I am working on a poc to write to hdfs files using BucketingSink class. Even thought I am
the data is being writing to hdfs files, but the files are lying with “.pending” on hdfs.

Below is the code I am using. Can someone pls help me identify the issue and help me fix this

BucketingSink<String> HdfsSink = new BucketingSink<String>("hdfs://xxxx/xxxx/xxxx/Test/");
HdfsSink.setBucketer(new DateTimeBucketer<String>("yyyy-MM-dd--HHmm"));
HdfsSink.setBatchSize(1024 * 1024 * 2); // this is 2 MB,

Thanks a lot.
