Description

In Cell interface (hbase-common/src/main/java/org/apache/hadoop/hbase/Cell.java)
(1) We have the following comment for "qualifier"

/**
  * 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.
  */

But getQualifierLength() returns int

int getQualifierLength();

(2) We have the following comment for "value"

  /**
   * Contiguous raw bytes that may start at any index in the containing array. Max length is
   * Integer.MAX_VALUE which is 2,147,483,648 bytes.
   * @return The array containing the value bytes.
   */

Integer.MAX_VALUE is not 2,147,483,648 (2^31), but 2,147,483,647 (2^31-1)
