Sahil Takiar resolved IMPALA-8428. ---------------------------------- Resolution: Fixed Fix Version/s: Impala 3.3.0 > Add support for caching file handles on s3 > ------------------------------------------ > > Key: IMPALA-8428 > URL: https://issues.apache.org/jira/browse/IMPALA-8428 > Project: IMPALA > Issue Type: Improvement > Components: Backend > Affects Versions: Impala 3.3.0 > Reporter: Joe McDonnell > Assignee: Sahil Takiar > Priority: Critical > Fix For: Impala 3.3.0 > > > The file handle cache is currently disabled for S3, as the S3 connector > needed to implement proper unbuffer support. Now that > https://issues.apache.org/jira/browse/HADOOP-14747 is fixed, Impala should > provide an option to cache S3 file handles. > This is particularly important for data caching, as accessing the data cache > happens after obtaining a file handle. If getting a file handle is slow, the > caching will be less effective. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
