Q: in the hive to run a select statement select col1, col2 from table start graphs appear the following error:
Java. Lang. IllegalArgumentException: Can not create a Path from an empty string at org. Apache
.
Perform select * can be normal, but just because the statement will not start the graphs, so there is a problem,

The current solution is: restart HDFS. Specific what is the cause of the error, lead to can't start the graphs,
