Description
Importing a heavy amount of data into a single table and family.
One column in that family (the same fam:col for every row) contains a frequently large amount of UTF-8 data. This column grows and grows but never causes a region split.
Currently there is a single mapfile containing nearly 10GB.
Eventually this has caused regions to crash with OOME, as described in HBASE-706
Table in question:
