------------------------------------------------
Summary: Scan after local index creation on table having data
giving wrong results when long view index id disabled
Key: PHOENIX-5550
URL: https://issues.apache.org/jira/browse/PHOENIX-5550
Project: Phoenix
Issue Type: Bug
Reporter: Rajeshbabu Chintaguntla
Assignee: Rajeshbabu Chintaguntla
Fix For: 4.15.0, 5.1.0
After PHOENIX-3547 and PHOENIX-5104 querying after local index creation on the
table having data is failing because of the view index id type mismatches.
The client is sending the SMALLINT as view index id data type.
{noformat}
private PDataType getViewIndexDataType() throws SQLException {
boolean supportsLongViewIndexId =
connection.getQueryServices().getProps().getBoolean(
QueryServices.LONG_VIEW_INDEX_ENABLED_ATTRIB,
QueryServicesOptions.DEFAULT_LONG_VIEW_INDEX_ENABLED);
return supportsLongViewIndexId ? MetaDataUtil.getViewIndexIdDataType()
: MetaDataUtil.getLegacyViewIndexIdDataType();
}
{noformat}
But in the create index api in endpoint impl is considering LONG as view index
id data type.
{noformat}
PDataType dataType =
MetaDataUtil.getViewIndexIdDataType();
Object val = dataType.toObject(seqValue,
PLong.INSTANCE);
byte[] bytes = new byte[dataType.getByteSize() + 1];
dataType.toBytes(val, bytes, 0);
Cell indexIdCell =
PhoenixKeyValueUtil.newKeyValue(cell.getRowArray(),
cell.getRowOffset(), cell.getRowLength(),
cell.getFamilyArray(),
cell.getFamilyOffset(),
cell.getFamilyLength(),
VIEW_INDEX_ID_BYTES, 0,
VIEW_INDEX_ID_BYTES.length,
cell.getTimestamp(), bytes, 0,
bytes.length, cell.getType());
{noformat}
{noformat}
if (indexId != null) {
builder.setViewIndexId(indexId);
builder.setViewIndexIdType(PLong.INSTANCE.getSqlType());
}
{noformat}
Most of the local index tests failing If we set false value to the following
configuration.
<property>
<!--
We have some hardcoded viewIndex ids in the IT tests which assumes
viewIndexId is of type Long.
However the default viewIndexId type is set to "short" by default until we
upgrade all clients to support
long viewIndex ids.

<value>false</value>
