----------------------------------------
Summary: NullPointerException in select writetime(m[null])
Key: CASSANDRA-21248
URL: https://issues.apache.org/jira/browse/CASSANDRA-21248
Project: Apache Cassandra
Issue Type: Bug
Reporter: Nadav Har'El
Hi tried (on Cassandra 5.0.6) the statement
{color:#a31515}SELECT WRITETIME(m[null]) FROM tbl{color}{color:#a31515} WHERE
p='something'{color}
And got the error (in this case, I used the Cassandra Python driver):
{{E cassandra.cluster.NoHostAvailable: ('Unable to complete the operation
against any hosts', \{<Host: 127.14.107.38:9042 datacenter1>: <Error from
server: code=0000 [Server error] message="java.lang.NullPointerException">})}}
What I really expected is to get just "null" as a response (this is typical SQL
behavior of nulls - they are "infectious" and an operation on a null returns a
null), but I guess another reasonable behavior would be to get some sort of
clean InvalidRequestException. Getting a "NoHostAvailable" mentioning
java.lang.NullPointerException is clearly not the right thing.
