Subject [jira] [Issue Comment Deleted] (HADOOP-13345) S3Guard: Improved Consistency for S3A
Date Sat, 03 Feb 2018 03:09:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13345?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

shanyu zhao updated HADOOP-13345:
---------------------------------
    Comment: was deleted

(was: Part of this patch added "copy-dependencies" execution in hadoop-aws/pom.xml without
scope. This caused all test jars copied to the lib folder as well. 
  <execution>
  <phase>package</phase>
  <goals>
  <goal>copy-dependencies</goal>
  </goals>
  <configuration>
  <outputDirectory>${project.build.directory}/lib</outputDirectory>
  </configuration>
  </execution>
 
Should we limit the scope of the copy to runtime? e.g. add following to <configuration>
section:
<includeScope>runtime</includeScope>)

> This issue proposes S3Guard, a new feature of S3A, to provide an option for a stronger
consistency model than what is currently offered.  The solution coordinates with a strongly
consistent external store to resolve inconsistencies caused by the S3 eventual consistency
model.
