> FsInput to use openFile() API for cloud storage read performance
> ----------------------------------------------------------------

> Key: AVRO-3594
> URL: https://issues.apache.org/jira/browse/AVRO-3594
> Project: Apache Avro
> Issue Type: Improvement

>
> avro can now use the FileSystem.openFile() API to open a file on a hadoop
> filesystem connector (HADOOP-15229).
> by setting the file length and fadvise policy through opt() calls, the
> clients can
> * skip a HEAD request when opening a file
> * optimise the ranges of GET request for sequential access, even in clusters
> where s3a has been configured to use random iO (which some hive clusters do)
> filesystems/releases which don't recognise the options added in HADOOP-16202
> will ignore them; the api will fall back to classic open(path) API call if
> the connector doesn't have a custom implementation.
