[jira] [Updated] (BEAM-2790) Error while reading from Amazon S3 via
Hadoop File System
[ https://issues.apache.org/jira/browse/BEAM-2790?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ismaël Mejía updated BEAM-2790:
-------------------------------
Description:
If you try to use hadoop-aws with Beam to read from AWS S3 it breaks because S3AInputStream (the implementation of Hadoop's FSDataInputStream) is not ByteBufferReadable.
