Example 1 with GenericUDFToDate

use of org.apache.hadoop.hive.ql.udf.generic.GenericUDFToDate in project phoenix by apache.

the class IndexPredicateAnalyzer method getColumnExpr.

// Check if ExprNodeColumnDesc is wrapped in expr.
// If so, peel off. Otherwise return itself.
private ExprNodeDesc getColumnExpr(ExprNodeDesc expr) {
    if (expr instanceof ExprNodeColumnDesc) {
        return expr;
    }
    ExprNodeGenericFuncDesc funcDesc = null;
    if (expr instanceof ExprNodeGenericFuncDesc) {
        funcDesc = (ExprNodeGenericFuncDesc) expr;
    }
    if (null == funcDesc) {
        return expr;
    }
    GenericUDF udf = funcDesc.getGenericUDF();
    // check if its a simple cast expression.
    if ((udf instanceof GenericUDFBridge || udf instanceof GenericUDFToBinary || udf instanceof GenericUDFToChar || udf instanceof GenericUDFToVarchar || udf instanceof GenericUDFToDecimal || udf instanceof GenericUDFToDate || udf instanceof GenericUDFToUnixTimeStamp || udf instanceof GenericUDFToUtcTimestamp) && funcDesc.getChildren().size() == 1 && funcDesc.getChildren().get(0) instanceof ExprNodeColumnDesc) {
