-------------------------------
Summary: providing non-empty value for dfs.domain.socket.path in
libhdfs
Key: HAWQ-1788
URL: https://issues.apache.org/jira/browse/HAWQ-1788
Project: Apache HAWQ
Issue Type: Improvement
Components: libhdfs
Reporter: Yuan Zhou
Assignee: Ruilong Huo
Hi HAWQ developers,
trying to enable the short-circuit read feature here and i found the default
value for dfs.domain.socket.path is empty string
[https://github.com/apache/hawq/blob/master/depends/libhdfs3/src/common/SessionConfig.cpp#L151]
it looks better to provide an aligned value with the documents from HDFS:
[https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/ShortCircuitLocalReads.html]
This would allow users to test against vanilla HDFS setup quickly.
