Full ERROR Message Example

The following may be seen when using SSTable tools in Cassandra and DSE

A full error stack was not available However the following will be part of the Error output

Failure serializing partition key. <IO error details>

What does this ERROR message mean?

This error occurs when the conversion of the partition key to json format fails

Why does this ERROR occur?

When using the SSTable tools like sstabledump, the output is typically output in json format. As part of this we need to read in the partition key in order to construct the row information and output in json format. If a problem occurs reading the partition key, we will see this error message

How do you fix this ERROR?

As with any SSTable corruption problem, the user might consider running tools such and nodetool scrub or sstablescrub. It is also possible to rebuild the node if it is suspected the corruption is widesparead (see uses of nodetool rebuild)
