Xiang Li commented on HBASE-16363:
----------------------------------
[~anoop.hbase], thanks for the comments!
bq.Though the type is int, the Q length can not be Int.max any way
Regarding "can not be Int.max", do you mean that is a JVM limitation or HBase
limitation?
Restricted by HotSpot JVM limitation, array max length is Integer.MAX_VALUE -
5, or a similar number, which depends on the platform and JVM version.
I see some discussion here
https://www.quora.com/What-is-the-maximum-size-of-the-array-in-Java
or on Stack Overflow
http://stackoverflow.com/questions/3038392/do-java-arrays-have-a-maximum-size
Or do you mean that HBase can not support qualifier length to be greater that
Short.MAX_VALUE? I read some Cell implementations, such as KeyValue, seems
qualifier length can be greater than Short.MAX_VALUE, at least there is no such
limitation in the code
> Length of column qualifier in Cell is a short or int

> Project: HBase
> Issue Type: Bug
> Components: documentation
> Reporter: Xiang Li

> Priority: Minor

> In Cell interface
> (hbase-common/src/main/java/org/apache/hadoop/hbase/Cell.java)
> In the comment, we have
> {code}
> /**
> * Contiguous raw bytes that may start at any index in the containing array.
> Max length is
> * Short.MAX_VALUE which is 32,767 bytes.
> * @return The array containing the qualifier bytes.

> {code}
> The length of the qualifier is a short
> But getQualifierLength() returns int
> {code}
> int getQualifierLength();
> {code}
> Which one is correct?
