Chris Nauroth resolved HADOOP-14301. ------------------------------------ Resolution: Fixed Hadoop Flags: Reviewed Fix Version/s: 2.9.0 +1 and committed to branch-2. [~liuml07], thank you for the patch. > Deprecate SharedInstanceProfileCredentialsProvider in branch-2. > --------------------------------------------------------------- > > Key: HADOOP-14301 > URL: https://issues.apache.org/jira/browse/HADOOP-14301 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3 > Reporter: Mingliang Liu > Assignee: Mingliang Liu > Fix For: 2.9.0 > > Attachments: HADOOP-14248-branch-2.002.patch > > > [HADOOP-13727] added the {{SharedInstanceProfileCredentialsProvider}}, which > effectively reduces high number of connections to EC2 Instance Metadata > Service caused by {{InstanceProfileCredentialsProvider}}. That patch, in > order to prevent the throttling problem, defined new class > {{SharedInstanceProfileCredentialsProvider}} as a subclass of > {{InstanceProfileCredentialsProvider}}, which enforces creation of only a > single instance. > Per [HADOOP-13050], we upgraded the AWS Java SDK. Since then, the > {{InstanceProfileCredentialsProvider}} in SDK code internally enforces a > singleton. {{SharedInstanceProfileCredentialsProvider}} can be deprecated as > of release 2.9.0. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
