Subject [jira] [Commented] (HADOOP-10640) Implement Namenode RPCs in HDFS native client
Date Thu, 05 Jun 2014 18:49:02 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10640?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14019090#comment-14019090
] 

Colin Patrick McCabe commented on HADOOP-10640:
-----------------------------------------------

bq. /root/hadoop-common/hadoop-native-core/src/main/native/ndfs/ndfs.c:315: warning: ‘defaults.blocksize’
may be used uninitialized in this function

It's a spurious warning, since {{ndfs_get_server_defaults}} will either return an error or
set {{defaults.blocksize}}.  But I'll add a {{memset}} to avoid it.  This will also make things
cleaner if we add more elements to the defaults structure in the future.

bq. #if defined(unix) || defined(__MACH__)

Hmm.  I thought that {{unix}} would be defined on MacOS.  I guess not.  I will add this--
thanks.
