             Summary: Trailing space in ZooKeeper serverList file trips some 
file systems
                 Key: GIRAPH-930
                 URL: https://issues.apache.org/jira/browse/GIRAPH-930
             Project: Giraph
          Issue Type: Bug
         Environment: HDInsight
            Reporter: Mostafa Elhemali
         Attachments: GIRAPH-930.diff

In Azure HDInsight (Hadoop in Microsoft Azure), the default file system is the 
WASB file system which places data on Azure blob storage. This file system 
doesn't handle trailing spaces that well, so when the ZooKeeperManager class 
tries to create the serverList file with a trailing space in there things fall 
apart.

Ideally WASB would handle trailing spaces, but in this case the trailing space 
is not really necessary. Can we remove it?
