> If a table has table/partition locations set to remote HDFS paths, querying them will
cause the following IAException:

> When the {{FileSystem}} instance is created, using the {{sessionConf}} implies that the
current HDFS is going to be used. This call should instead fetch the {{FileSystem}} instance
corresponding to the path being checked.
> A fix is forthcoming...
