Re: Syntax for filters on timstamp data type
Glad to hear, Steffan. Do you mind creating a JIRA for this at
https://issues.apache.org/jira?
Thanks in advance!

so can we assume that equals comparison can auto cast but not the in range

Steffan,
One thing that may be different is that equal can cast operands to make equals
work but that may not be true for IN. FWIW, this is me just speculating, I
haven't looked at the code just yet.
Perhaps, you could explicit casting to get around this?

RE: Syntax for filters on timstamp data type
Equal, not equal, less than, less or equal, greater than, greater or equal all
work. Also the function execution in the IN clause seems to work, as the error
message states that the result type is bigint. Following the error message, it
expects the input as timestamp, but I couldn't find a syntax to express
timestamps in HiveQL.
Two questions remain:
1) How to express timestamps in HiveQL?
2) Why doesn't the IN clause support comparisons between timestamp and
bigint, if "equal" and so on does?
