Hbase MAX_ROW_LENGTH value belongs to ?

[#1]

Hi ,

In one my application , i am getting illegalargument exception 38121 is > 32767 . so i found that MAX_ROW_LENGTH is having constant value of 32767 .

Here my question is MAX_ROW_LENGTH values is belongs to row key or only key length ?

as per this link https://hbase.apache.org/apidocs/org/apache/hadoop/hbase/HConstants.html#MAX_ROW_LENGTH , I unsrtood that it is belong to row length not key length ??

Please correct me if i am wrong .

It is the length of the row component of the Key.

means , it is length of row , not key length .

for better understanding , please take a look at below ex , row8 is the row-key value of a row , age=88,name=srini88,no=8 are the values of a row . so , here what will be the value which compares against the MAX_ROW_LENGTH . is it row8 length or whole row length(which is the combination of row8,88,srini88,8) ?

and Is MAX_ROW_LENGTH possible to modify in hbase-site or for specific table ? if yes , please let us know how it is ?

ex : row8 column=0:age, timestamp=1475378868472, value=88

row8 column=0:name, timestamp=1475378868438, value=srini8

row8 column=0:no, timestamp=1475378868384, value=8

Yes, the length of the row, not the entire key. The row component in the keys that you provided is "row8". Please refer to the HBase documentation if you are unclear on what components make up an HBase Key.
