Guangxu Cheng updated HBASE-21174: ---------------------------------- Environment: (was: {code:xml} GET /t1/*?column=f:c1&column=f: {code} 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. {code:java|title=TableResource#getScanResource|borderStyle=solid} 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])); } } {code} 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.) > [REST] Failed to parse empty qualifier in TableResource#getScanResource > ----------------------------------------------------------------------- > > Key: HBASE-21174 > URL: https://issues.apache.org/jira/browse/HBASE-21174 > Project: HBase > Issue Type: Bug > Components: REST > Affects Versions: 3.0.0, 2.2.0 > Reporter: Guangxu Cheng > Assignee: Guangxu Cheng > Priority: Major > > {code:title=TableResource#getScanResource|borderStyle=solid} > 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])); > } > } > {code} > {code:xml} > GET /t1/*?column=f:c1&column=f: > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
