-------------------------------------------------------------
As java client allows delete options with extra column set while c++ client
doesn't support this, I fould there may be a problem in encodeRow :
[https://github.com/apache/kudu/blob/07eb5a97f17046f6ee61b2a28bdfbe578d3f6d2b/java/kudu-client/src/main/java/org/apache/kudu/client/Operation.java#L365-L373]
java api doc of BitSet.clear(int fromIndex, int toIndex):
{quote}public void clear(int fromIndex, int toIndex)
Sets the bits from the specified {{fromIndex}} (inclusive) to the specified
{{toIndex}} (exclusive) to {{false}}.
{quote}
But why it works well with non-64-column tables?

> Unable to delete a full row from a table with 64 columns when using java

> Key: KUDU-3198
> URL: https://issues.apache.org/jira/browse/KUDU-3198
> Project: Kudu
> Issue Type: Bug
> Components: java
> Affects Versions: 1.12.0, 1.13.0
> Reporter: YifanZhang
> Priority: Major
>
> We recently got an error when deleted full rows from a table with 64 columns
> using sparkSQL, however if we delete a column, this error will not appear.
> The error is:
> {code:java}
> Failed to write at least 1000 rows to Kudu; Sample errors: Not implemented:
> Unknown row operation type (error 0){code}
> I tested this by deleting a full row from a table with 64 column using java
> client 1.12.0/1.13.0, if the row is set NULL for some columns, I got an error:
> {code:java}
> Row error for primary key=[-128, 0, 0, 1], tablet=null,
> server=d584b3407ea444519e91b32f2744b162, status=Invalid argument: DELETE
> should not have a value for column: c63 STRING NULLABLE (error 0)
> {code}
> if the row is set values for all columns , I got an error like:
> {code:java}
> Row error for primary key=[-128, 0, 0, 1], tablet=null, server=null,
> status=Corruption: Not enough data for column: c63 STRING NULLABLE (error 0)
> {code}
> I also tested this with tables with different number of columns. The weird
> thing is I could delete full rows from a table with 8/16/32/63/65 columns,
> but couldn't do this if the table has 64/128 columns.
