Hi Todd,

Can you check your master log and let me know if you see "Meta has HRI with HTDs. Updating meta now." and "Meta updated with new HRI." and "Updated -ROOT- row with metaMigrated status = true" ?

So, just FYI: 

We migrate old HRI's (i.e HRI with HTD information) to new HRI (with out HTD, and creating the HTD's in HDFS) at server startup for the first time and if the process is successful we also update -ROOT- with a flag metaMigrated=true.

Based on your symptoms it seems to me that either the migration did not go through properly, or some thing else is missing, and we need to troubleshoot further to determine the root cause and the resolution.

Please let me know what you see in your logs and also if possible post your logs.

thanks
Subbu

> I started a trunk cluster as an upgrade from 0.90.4ish, and now my META table is screwed. I can't scan it, etc, and other operations fail.
