Hi,
Has anyone loaded data from HDFS? I met a problem when loading data use
following query:
use dataverse tpcds3;
load dataset inventory
using hdfs(("hdfs"="hdfs://SCAI01.CS.UCLA.EDU:9000
<http://scai01.cs.ucla.edu:9000/>"),("path"="/clash/datasets/tpcds/10/
inventory"),("format"="delimited-text"),("delimiter"="|"));
The Error in web interface is:
Internal error. Please check instance logs for further details.
[NullPointerException]
I check the cc.log (cluster controller) and find the following problem:
SEVERE: Unable to create adapter
org.apache.hyracks.algebricks.common.exceptions.AlgebricksException: Unable
to create adapter
at org.apache.asterix.metadata.declared.AqlMetadataProvider.
getConfiguredAdapterFactory(AqlMetadataProvider.java:990)
at org.apache.asterix.metadata.declared.LoadableDataSource.
buildDatasourceScanRuntime(LoadableDataSource.java:141)
More about the log is in the attachment.
I think there is no problem about the syntax of query. Does anyone have
idea about this?
Thanks,
Mingda
