Hard to say how balanced the table is. We have a mixed requirement where we want some locality for timeseries queries against "clusters" of information. However the "clusters" in a table are should be well distributed if the dataset is large enough.
The query in question killed 5 RSs so I am inferring either: 1) the table was spread across these 5 RSs 2) the query moved around on the cluster as RSs failed Perhaps you could tell me if #2 is possible.

What release of HBase are you using ?

We traced this back to a client calling Table.get(List<Get> gets) with a collection containing ~4000 individual gets. We've worked around this by limiting the number of Gets we send in a single call to Table.get(List<Get>) Is there some configuration parameter that we are missing here? Thanks, Ted
