Description

When cloning a table, there's an option to exclude certain properties from being copied over. When those excluded properties are processed in clone() in TableOperations, they are passed as options with a key and a null value. When passed through Thrift, the null value isn't expected because it uses the same process to set properties as well. Here's a stack trace.
