Venkatesh Seetharam commented on FALCON-169:
--------------------------------------------
Thanks [~shwethags] and [~samarthg] for looking into this. But I wonder how
there can be multiple '//' in the path. The code normalizes it as below:
{code}
private void propagateFileSystemCopyProperties(String
pathsWithPartitions,
Map<String, String>
props) throws FalconException {
String parts = pathsWithPartitions.replaceAll("//+", "/");
parts = StringUtils.stripEnd(parts, "/");
props.put("sourceRelativePaths", parts);
props.put("distcpSourcePaths", "${coord:dataIn('input')}");
props.put("distcpTargetPaths", "${coord:dataOut('output')}");
}
{code}
sourceRelativePaths is substituted for falcon.include.path.
{code}
<main-class>org.apache.falcon.replication.FeedReplicator</main-class>
<arg>-Dfalcon.include.path=${sourceRelativePaths}</arg>
{code}
I must be missing something here.
