-------------------------------------
Summary: Add support for caching file handles on s3
Key: IMPALA-8428
URL: https://issues.apache.org/jira/browse/IMPALA-8428
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 3.3.0
Reporter: Joe McDonnell
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.
