Yerui Sun created KYLIN-1216:
--------------------------------
Summary: Can't parse DateFormat like 'YYYYMMDD' correctly
Key: KYLIN-1216
URL: https://issues.apache.org/jira/browse/KYLIN-1216
Project: Kylin
Issue Type: Bug
Components: Query Engine
Affects Versions: 1.2, 2.0
Reporter: Yerui Sun
Assignee: Yerui Sun
Fix For: 1.2, 2.0
Kylin has support date format as 'YYYYMMDD' since KYLIN-1101, and could read
data and build cube successfully with this format.
However, the query sql contains " dt='20151208' " can't be parsed, the reason
is HBaseKeyRange.initPartitionRange still using default format 'YYYY-MM-DD'
only, not read from partition desc.
Here's the trace:
{code}
Caused by: java.lang.IllegalArgumentException: '20150901' is not a valid date
of pattern 'yyyy-MM-dd'
