Virajith Jalaparti created HDFS-12777:
-----------------------------------------
Summary: [READ] Share URI prefix across Provided blocks to lower
memory footprint.
Key: HDFS-12777
URL: https://issues.apache.org/jira/browse/HDFS-12777
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Virajith Jalaparti
Priority: Major
As opposed to local blocks, each DN keeps track of all blocks in PROVIDED
storage. This can be millions of blocks for 100s of TBs of PROVIDED data. This
JIRA aims to reduce the memory footprint of these blocks by using a common URI
prefix across all PROVIDED blocks.
