Mithun Radhakrishnan updated HIVE-14380:
----------------------------------------
Description:
If a table has table/partition locations set to remote HDFS paths, querying
them will cause the following IAException:
{noformat}
2016-07-26 01:16:27,471 ERROR parse.CalcitePlanner
(SemanticAnalyzer.java:getMetaData(1867)) -
org.apache.hadoop.hive.ql.metadata.HiveException: Unable to determine if
hdfs://foo.ygrid.yahoo.com:8020/projects/my_db/my_table is encrypted:
java.lang.IllegalArgumentException: Wrong FS:

org.apache.hadoop.hive.ql.parse.SemanticAnalyzer.getStrongestEncryptedTablePath(SemanticAnalyzer.java:2274)

{noformat}
This is because of the following code in {{SessionState}}:
{code:title=SessionState.java|borderStyle=solid}
public HadoopShims.HdfsEncryptionShim getHdfsEncryptionShim() throws
HiveException {
if (hdfsEncryptionShim == null) {
try {
FileSystem fs = FileSystem.get(sessionConf);
if ("hdfs".equals(fs.getUri().getScheme())) {
hdfsEncryptionShim =
ShimLoader.getHadoopShims().createHdfsEncryptionShim(fs, sessionConf);
} else {
LOG.debug("Could not get hdfsEncryptionShim, it is only applicable to
hdfs filesystem.");
}
} catch (Exception e) {
throw new HiveException(e);
}
}
return hdfsEncryptionShim;
}
{code}
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...
