我正在运行以下失败的 HBASE shell 脚本，但我不知道为什么：
import org.apache.hadoop.hbase.filter.CompareFilter
import org.apache.hadoop.hbase.filter.SubstringComparator
a = ARGV[0]
myscan="'dcqa_event_agg', {FILTER => org.apache.hadoop.hbase.filter.RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new('" + a + "'))}" + "\n"
scan myscan
exit
dcqa_event_agg 行存在。当我运行命令时：
hbase shell filtertest.rb 2013
我收到以下错误：
ERROR: Unknown table 'dcqa_event_agg', {FILTER => org.apache.hadoop.hbase.filter.RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new('2013'))}
当我直接在 HBASE shell 中运行脚本时，它工作正常。有任何想法吗？
我在 shell 脚本中添加了一些调试：
import org.apache.hadoop.hbase.filter.CompareFilter
import org.apache.hadoop.hbase.filter.SubstringComparator
a = ARGV[0]
myscan="'dcqa_event_agg', {FILTER => org.apache.hadoop.hbase.filter.RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new('" + a + "'))}"
print myscan + "\n"
print "scan " + myscan + "\n"
scan myscan
exit
这是输出：
[test ~]$ hbase shell filtertest.rb 2013
13/08/23 18:08:44 WARN conf.Configuration: hadoop.native.lib is deprecated. Instead, use io.native.lib.available
'dcqa_event_agg', {FILTER => org.apache.hadoop.hbase.filter.RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new('2013'))}
scan 'dcqa_event_agg', {FILTER => org.apache.hadoop.hbase.filter.RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new('2013'))}
ERROR: Unknown table 'dcqa_event_agg', {FILTER => org.apache.hadoop.hbase.filter.RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new('2013'))}!
删除引号并没有解决它。
如果我在 hbase shell 环境中运行命令：
import org.apache.hadoop.hbase.filter.CompareFilter
import org.apache.hadoop.hbase.filter.SubstringComparator
scan 'dcqa_event_agg', {FILTER => org.apache.hadoop.hbase.filter.RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new('2013'))}
我没有得到错误。
