Marc Harris updated HBASE-428:
------------------------------
Attachment: 428-v5.patch
428-v4.patch was made against slightly the wrong version. v4 included the
removal of some commented out code in HRegionServer.java that caused the patch
to fail (the code was already removed in the official 0.16.0-rc1 release
> Under continuous upload of rows, WrongRegionExceptions are thrown that reach
> the client even after retries

> I have installed 0.16.0 rc 1 which I believe contains a fix for similar issue
> HBASE-138, but I still see the same problem.
> - I am using a single node.
> - The client application runs in a single thread, loading data into a single
> table.
> - I get good throughput of about 200 rows/sec to start with, with occasional
> significant drops due to NotServingRegionException's that are recoverable on
> client retry (internal to hbase).
> - After 54 minutes, and about 500,000 rows I start to see
> WrongRegionException's in the client application, i.e. real failures. (Note
> that this compares to 0.15.3 which would being to throw
> NotServingRegionExceptions after a few tens of thousands of rows).
> My data consists of a single table with 5 column families. The data written
> is as follows:>>
> key: a URL
> family 1: a small string, often emty, 2 longs, 1 int
> family 2: a byte averaging averaging between 1k and 10k, a small string
> family 3: several columns with different names per row, values of small
> strings
> family 4: most rows have zero columns, some rows have 1 or more columns with
> a UL value
> The URLs are typically "long-ish" URL as seen when crawling a site, not short
> home page URLs
>
> I am assuming the data is stored in files of the form
> <hbaseroot>//<tablename>/<9digitnum>/data/mapfiles/<19digitnum>/data. I have
> attached a csv file showing the distribution of size of these files. Average
> size is 19Mb, but the sizes are not evenly distributed at all
> Here are two sample exceptions thrown, copied from the region server log:
