------------------------------------------
Summary: Upgrade to 4.0 fails with NullPointerException
Key: CASSANDRA-14820
URL: https://issues.apache.org/jira/browse/CASSANDRA-14820
Project: Cassandra
Issue Type: Bug
Components: 4.0
Reporter: Tommy Stendahl
I tested to upgrade an existing cluster to latest 4.0 but it fails with a
NullPointerException, I upgraded from 3.0.15 but upgrading from any 3.0.x or
3.11.x to 4.0 will give the same fault.

The problem seams to be line 997 in SchemaKeyspace.java
{noformat}
.speculativeWriteThreshold(SpeculativeRetryPolicy.fromString(row.getString("speculative_write_threshold"{noformat}
speculative_write_threshold is a new table option introduced in
CASSANDRA-14404, when upgrading the table option is missing and we get a
NullPointerException on this line.
