Subject java.lang.IllegalArgumentException in incrementColumnValue and Increment
Date Tue, 29 Mar 2011 15:22:22 GMT
Hi,

Unable to use the Increment function, can anybody suggest what am I doing
wrong...

I enter data by :-
theput.add(Bytes.toBytes("uid"),Bytes.toBytes("1"), 1301087829999L + t,
Bytes.toBytes(10))

Now when I try to increment the value I have tried...
mytable.incrementColumnValue(Bytes.toBytes("row5"),
Bytes.toBytes("uid"),Bytes.toBytes("1"),Bytes.toBytes(1))
mytable.incrementColumnValue(Bytes.toBytes("row5"),
Bytes.toBytes("uid"),Bytes.toBytes("1"),1)

also
val inc = new Increment(Bytes.toBytes("row" + 5))
inc.addColumn(Bytes.toBytes("uid"),Bytes.toBytes("1"),1)
mytable.increment(inc)

In both of the cases, I get an error like
org.apache.hadoop.hbase.client.RetriesExhaustedException:
Exceptions:
java.io.IOException: java.io.IOException:
java.lang.IllegalArgumentException: offset (28) + length (8) exceed the
capacity of the array: 32

I guess I have tried all possible combinations of datatypes....I could not
even find a decent example of incrementColumnValue()
