------------------------------------
Summary: Make libhdfs3 binary compatible with libhdfs
Key: HAWQ-1624
URL: https://issues.apache.org/jira/browse/HAWQ-1624
Project: Apache HAWQ
Issue Type: Improvement
Components: libhdfs
Reporter: Sergei Lebedev
Assignee: Radar Lei
libhdfs3 is almost binary compatible with libhdfs. The missing bits are:
* libhdfs3 does not define hdfsPread which nonetheless can be implemented in
terms of hdfsTell, hdfsSeek and hdfsRead;
* hdfsSync is called hdfsHSync in libhdfs3;
* In libhdfs hdfsFlush flushes the internal buffer of the BufferedInputStream;
in libhdfs3 it always flushes to HDFS, i.e. it does what hdfsHFlush should do.
