[jira] [Updated] (HIVE-20471) issues getting the default database
path
[ https://issues.apache.org/jira/browse/HIVE-20471?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sergey Shelukhin updated HIVE-20471:
------------------------------------
Description:
{noformat}
Caused by: java.lang.IllegalArgumentException: Can not create a Path from an empty string
at org.apache.hadoop.fs.Path.checkPathArg(Path.java:168)
at org.apache.hadoop.fs.Path.<init>(Path.java:237)
at org.apache.hadoop.hive.metastore.Warehouse.getDnsPath(Warehouse.java:143)
at org.apache.hadoop.hive.metastore.Warehouse.getDnsPath(Warehouse.java:147)
at org.apache.hadoop.hive.metastore.Warehouse.getWhRoot(Warehouse.java:160)
at org.apache.hadoop.hive.metastore.Warehouse.getDatabasePath(Warehouse.java:235)
at org.apache.hadoop.hive.ql.parse.SemanticAnalyzer.getMetaData(SemanticAnalyzer.java:2335)
at org.apache.hadoop.hive.ql.parse.SemanticAnalyzer.getMetaData(SemanticAnalyzer.java:2074)
{noformat}
given that the path passed to getDnsPath is already a path that is probably valid, this method needs to be a little bit more reliable. Not sure which argument turns out to be empty, but I wonder why this complexity is needed for the default database.
Of note: this only affects CTAS for me.
I can create a table and insert data and it works fine; location is hdfs://[...].hortonworks.com:8020/warehouse/
