Subject [jira] [Updated] (HADOOP-13926) S3Guard: Improve listLocatedStatus and listFiles
Date Fri, 31 Mar 2017 01:42:41 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13926?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mingliang Liu updated HADOOP-13926:
-----------------------------------
    Attachment: HADOOP-13926-HADOOP-13345.001.patch

I rebase and updated [~rajesh.balamohan]'s wip patch. Let's get this initial patch in, and
hopefully it will unblock [HADOOP-13998] initial preview, and thus merging back to trunk.
As future work (part of [HADOOP-14000]), we have to revise this in two ways: 1) use paging
for listing children from metadata store 2) for non-auth, union the results from S3 and metadata
store, and populates to metadata store.

Tested against us-west-1 region:
{code}
$ mvn -Dit.test='ITestS3A*,ITestS3Guard*,ITestDynamo*' -Dtest=none -Dscale -Ds3guard -Ddynamo
-q clean verify

Results :

Tests run: 357, Failures: 0, Errors: 0, Skipped: 16
{code}

> Need to check if {{listLocatedStatus}} can make use of metastore's listChildren feature.
