[jira] [Updated] (HADOOP-14580) Sample mount table in ViewFs.md
contains capitalization error
[ https://issues.apache.org/jira/browse/HADOOP-14580?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Todd Owen updated HADOOP-14580:
-------------------------------
Description:
In this file: https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/site/markdown/ViewFs.md
The rest of the document refers to {{clusterX}}, but the sample mount table uses the incorrect capitalisation {{ClusterX}}.
It took me a little while to figure out why my experiments were not working. This is compounded by the fact that errors from viewfs are not very descriptive, e.g.:
{noformat}
$ hdfs dfs -ls /
ls: viewfs://clusterX/
$ hdfs dfs -cat /xyz
cat: viewfs://clusterX/
{noformat}
Suggested fix is to replace the 5 instances of {{ClusterX}} with {{clusterX}}. And ideally improve the error message to something like:
{noformat}
$ hdfs dfs -ls /
ls: viewfs://clusterX/: No such property fs.viewfs.mounttable.clusterX.link.*
{noformat}
