-----------------------------------------
Summary: Lower HConstants#MAX_ROW_LENGTH as guardrail in order to
avoid HBASE-18987
Key: HBASE-19309
URL: https://issues.apache.org/jira/browse/HBASE-19309
Project: HBase
Issue Type: Bug
Components: HFile, regionserver
Reporter: Esteban Gutierrez
As discussed in HBASE-18987. A problem of having a row about the maximum size
of a row (Short.MAX_VALUE) is when a split happens, there is a possibility that
the midkey could be that row and the Put created to add the new entry in META
will exceed the maximum row size since the new row key will include the table
name and that will cause the split to abort. Since is not possible to raise
that row key size in HFileV3, a reasonable solution is to reduce the maximum
size of row key in order to avoid exceeding Short.MAX_VALUE.
