where is the source code kylin-2.0.0-hbase1x
hi,all: In http://kylin.apache.org/download/ apache-kylin-2.0.0-bin-hbase098.tar.gz source code in: https://github.com/apache/kylin/ tag：* kylin-2.0.0-hbase0.98* 。 But I can't find tag : *apache-kylin-2.0.0-bin-hbase1x * in github so where is the source code* apache-kylin-2.0.0-hbase1x*? which hbase version is tag* kylin-2.0.0 * ? -- * Best Wishes*
Re: kylin sql query with Weird error
hi，all：
thanks for kyligence's help, I have finded the reason of this problem：
hbase 1.1.2 bug: https://issues.apache.org/jira/browse/HBASE-14269
After we upgrade the cluster to hbase 1.1.8, the sql query is ok.
So the solution is to upgrade hbase version, thanks billyliu 。

Re: kylin sql query with Weird error
HI, I am sure hbase is ok.
而且只有这个sql抛异常，且能稳定复现。 sql稍微改一下，就正常。
从异常日志看， 首先抛出异常的是
Caused by: java.lang.NullPointerException
at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:191)
at
org.apache.kylin.storage.hbase.cube.v2.HBaseReadonlyStore$1$1.next(HBaseReadonlyStore.java:131)
对应于 代码：
Pair hbaseColumn = hbaseColumns.get(i);
Cell cell = findCell(oneRow, hbaseColumn.getFirst(), hbaseColumn.getSecond());
Preconditions.checkNotNull(cell);
cell 啥时候 会为空？

上面这个ｓｑｌ执行ＯＫ，符合预期。
