-----------------------------------

             Summary: Über-jira adl:// Azure Data Lake Phase II: Performance and Testing
                 Key: HADOOP-14764
                 URL: https://issues.apache.org/jira/browse/HADOOP-14764
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/adl
    Affects Versions: 3.0.0-alpha2
            Reporter: John Zhuge
            Assignee: John Zhuge


Uber JIRA to track things needed for Azure Data Lake to be considered stable and adl:// ready
for wide use.

Based on the experience with other object stores, the things which usually surface once a
stabilizing FS is picked up and used are

* handling of many GB files, up and down, be it: efficiency of read, when the writes take
place, file leakage, time for close() and filesystem shutdown
* resilience to transient failures
* reporting of problems/diagnostics
* security option tuning
* race conditions
* differences between implementation and what actual applications expect
