Re: Table dead lock: ERROR 1120 (XCL20): Writes to table blocked until index can be updated

Tue, 02 Oct 2018 12:03:02 -0700

HBase will invalidate the location of a Region on seeing certain exceptions (including NotServingRegionException). After it sees the exception you have copied below, it should re-fetch the location of the Region.
If HBase keeps trying to access a Region on a RS that isn't hosting it, either hbase:meta is wrong or the HBase client has a bug. 


However, to the point here, if that region was split successfully, 
clients should not be reading from that region anymore -- they would 
read from the daughters of that split region.

Is there any way to invalidate meta-cache on event of index regions 
split? Maybe there is some option to set max time to live for cache?

    Looks like lock goes away 30 minutes after index region split.
    So i can assume that this issue comes from cache that configured
    by this option:*phoenix.coprocessor.maxMetaDataCacheTimeToLiveMs*
