> When the query is served by the index and the scan has a skipscan filter, the
> query fails with the exception:
> {code:java}
> Caused by: java.lang.IllegalStateException: The next hint must come after
> previous hint (prev=val1\x00val2d//LATEST_TIMESTAMP/Maximum/vlen=0/seqid=0,
> next=val1\x00val2d//LATEST_TIMESTAMP/Maximum/vlen=0/seqid=0,
> kv=val1\x00val2c\x00c/0:\x00\x00\x00\x00/1752538149585/Put/vlen=1/seqid=8) at

> This is happening because when an index row is unverified, the read repair
> process can in some cases rewind the scanner which violates the state of the
> skipscan filter and the skipscan filter throws an IllegalStateException
