[jira] [Commented] (HIVE-15857) Vectorization: Add string
conversion case for UDFToInteger, etc
[ https://issues.apache.org/jira/browse/HIVE-15857?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15859152#comment-15859152 ]
Matt McCline commented on HIVE-15857:
-------------------------------------
Without the new CastStringToLong class, conversion falls to VectorUDFAdaptor.
{code}
vector.VectorExpressionDescriptor: getVectorExpressionClass udf UDFToInteger descriptor: Argument Count = 1, mode = PROJECTION, Argument Types = {STRING}, Input Expression Types = {COLUMN}
vector.VectorExpressionDescriptor: getVectorExpressionClass doesn't match CastTimestampToLong Argument Count = 1, mode = PROJECTION, Argument Types = {TIMESTAMP}, Input Expression Types = {COLUMN}
vector.VectorExpressionDescriptor: getVectorExpressionClass doesn't match CastDoubleToLong Argument Count = 1, mode = PROJECTION, Argument Types = {FLOAT_FAMILY}, Input Expression Types = {COLUMN}
vector.VectorExpressionDescriptor: getVectorExpressionClass doesn't match CastDecimalToLong Argument Count = 1, mode = PROJECTION, Argument Types = {DECIMAL}, Input Expression Types = {COLUMN}
vector.VectorizationContext: No vector udf found for UDFToInteger, descriptor: Argument Count = 1, mode = PROJECTION, Argument Types = {STRING}, Input Expression Types = {COLUMN}
vector.VectorizationContext: We will try to use the VectorUDFAdaptor for GenericUDFBridge ==> UDFToInteger (Column[tmp_values_col1]) because hive.vectorized.adaptor.usage.mode=all
{code}
