GET /t1/*?column=f:c1&column=f:
If I want to get the values of 'f:'(empty qualifier) for all rows in the table by rest server, I will send the above request. However, this request will return all column values.
TableResource#getScanResource
for (String csplit : column) { String[] familysplit = csplit.trim().split(":"); if (familysplit.length == 2) { if (familysplit[1].length() > 0) { if (LOG.isTraceEnabled()) { LOG.trace("Scan family and column : " + familysplit[0] + " " + familysplit[1]); } tableScan.addColumn(Bytes.toBytes(familysplit[0]), Bytes.toBytes(familysplit[1])); } else { tableScan.addFamily(Bytes.toBytes(familysplit[0])); if (LOG.isTraceEnabled()) { LOG.trace("Scan family : " + familysplit[0] + " and empty qualifier."); } tableScan.addColumn(Bytes.toBytes(familysplit[0]), null); } } else if (StringUtils.isNotEmpty(familysplit[0])) { if (LOG.isTraceEnabled()) { LOG.trace("Scan family : " + familysplit[0]); } tableScan.addFamily(Bytes.toBytes(familysplit[0])); } }
Through the above code, when the column has an empty qualifier, the empty qualifier cannot be parsed correctly.In other words, 'f:'(empty qualifier) and 'f' (column family) are considered to have the same meaning, which is wrong.
