    Reproduction steps above. This error can occur whenever fields from a CSV step using lazy initialization are passed to a Memory Group By step. The error below will occur. This appears to happen because of a mismatch in the ValueMeta data and storage type. The value is converted to normal storage in MemoryGroupBy.addToAggregate, but its storage type remains binary. {noformat} 2015/12/22 12:56:31 - Memory Group by.0 - ERROR (version 6.1.0.0-98, build 1 from 2015-12-15 22.48.55 by buildguy) : Unexpected error 2015/12/22 12:56:31 - Memory Group by.0 - ERROR (version 6.1.0.0-98, build 1 from 2015-12-15 22.48.55 by buildguy) : java.lang.RuntimeException: Unable to verify if [field String<binary-string>] is null or not because of an error:java.lang.ClassCastException: java.lang.String cannot be cast to [B 2015/12/22 12:56:31 - Memory Group by.0 - at org.pentaho.di.core.row.value.ValueMetaBase.isNull(ValueMetaBase.java:3337) 2015/12/22 12:56:31 - Memory Group by.0 - at org.pentaho.di.core.row.value.ValueMetaBase.compare(ValueMetaBase.java:3370) 2015/12/22 12:56:31 - Memory Group by.0 - at org.pentaho.di.core.row.RowMeta.compare(RowMeta.java:991) 2015/12/22 12:56:31 - Memory Group by.0 - at org.pentaho.di.trans.steps.memgroupby.MemoryGroupByData$HashEntry.equals(MemoryGroupByData.java:54) 2015/12/22 12:56:31 - Memory Group by.0 - at java.util.HashMap.getNode(HashMap.java:571) 2015/12/22 12:56:31 - Memory Group by.0 - at java.util.HashMap.get(HashMap.java:556) 2015/12/22 12:56:31 - Memory Group by.0 - at org.pentaho.di.trans.steps.memgroupby.MemoryGroupBy.addToAggregate(MemoryGroupBy.java:242) 2015/12/22 12:56:31 - Memory Group by.0 - at org.pentaho.di.trans.steps.memgroupby.MemoryGroupBy.processRow(MemoryGroupBy.java:175) 2015/12/22 12:56:31 - Memory Group by.0 - at org.pentaho.di.trans.step.RunThread.run(RunThread.java:62) 2015/12/22 12:56:31 - Memory Group by.0 - at java.lang.Thread.run(Thread.java:745) 2015/12/22 12:56:31 - Memory Group by.0 - Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to [B 2015/12/22 12:56:31 - Memory Group by.0 - at org.pentaho.di.core.row.value.ValueMetaBase.isNull(ValueMetaBase.java:3308) 2015/12/22 12:56:31 - Memory Group by.0 - ... 9 more {noformat}
