[jira] [Created] (HDFS-6930) Improve replica eviction from RAM disk

Arpit Agarwal created HDFS-6930:
-----------------------------------

             Summary: Improve replica eviction from RAM disk
                 Key: HDFS-6930
                 URL: https://issues.apache.org/jira/browse/HDFS-6930
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: HDFS-6581
            Reporter: Arpit Agarwal


The current replica eviction scheme is inefficient since it performs multiple file operations in the context of block allocation.

A better implementation would be asynchronous eviction when free space on RAM disk falls below a low watermark to make block allocation faster.
