-------------------------------------
Summary: ofs file input stream should support StreamCapabilities
interface
Key: HDDS-7135
URL: https://issues.apache.org/jira/browse/HDDS-7135
Project: Apache Ozone
Issue Type: Bug
Reporter: Wei-Chiu Chuang
To open a file in ofs, a file input stream is created. This file input stream
does not inherit from CapableOzoneFSInputStream which supports
StreamCapabilities interface where applications can query the capability
supported.
This is found by setting Impala front end log level "org.apache.hadoop" to ALL
through the impalad's /log_level endpoint, and then run queries that access
files in ofs.
The following log message will be seen:

org.apache.hadoop.fs.ozone.OzoneFSInputStream:
does not implement StreamCapabilities and the unbuffer capability
