Subject [jira] Created: (HBASE-3086) Treate BloomFilter Properly in HBase Shell
Date Wed, 06 Oct 2010 19:30:33 GMT
Treate BloomFilter Properly in HBase Shell 
-------------------------------------------

                 Key: HBASE-3086
                 URL: https://issues.apache.org/jira/browse/HBASE-3086
             Project: HBase
          Issue Type: Bug
          Components: shell
    Affects Versions: 0.89.20100621
            Reporter: Karthick Sankarachary
            Priority: Minor


The HBase shell doesn't treat the value of the BLOOMFILTER in the column descriptor as a string.
Instead, it wrongly interprets it to be a boolean, which may have the case earlier. As a result,
we cannot create tables with bloom filter enabled, as the following example illustrates:

hbase(main):003:0> create 't1', { NAME => 'f1', BLOOMFILTER => 'ROWCOL' }

ERROR: no constructor with arguments matching [class org.jruby.java.proxies.ArrayJavaProxy,
class org.jruby.RubyFixnum, class org.jruby.RubyString, class org.jruby.RubyBoolean, class
org.jruby.RubyBoolean, class org.jruby.RubyFixnum, class org.jruby.RubyFixnum, class org.jruby.RubyBoolean,
class org.jruby.RubyFixnum] on object #<Java::OrgApacheHadoopHbase::HColumnDescriptor:0x4e695527>

To fix this issue, we should change the "hcd" method in the hbase/admin.rb class, so that
it doesn't try to treat the bloom filter as a boolean (see diff below and patch attached).

-        arg.include?(HColumnDescriptor::BLOOMFILTER)? JBoolean.valueOf(arg[HColumnDescriptor::BLOOMFILTER]):
HColumnDescriptor::DEFAULT_BLOOMFILTER,
+        arg.include?(HColumnDescriptor::BLOOMFILTER)? arg[HColumnDescriptor::BLOOMFILTER]:
HColumnDescriptor::DEFAULT_BLOOMFILTER,
