Arpit Agarwal updated HDFS-8192:
--------------------------------
Description:
Eviction from RAM disk will be triggered when locked memory is insufficient RAM
to allocate a new replica for writing.
This is a follow up to HDFS-8157. We no longer need the threshold configuration
keys since we won't be evicting based on thresholds any more.
