> However, the problem can also be reproduced in latest master branch. Further
> investigation shows that the following code (in ParseUtils.java) is
> problematic:
> {code}
> static int getIndex(String[] list, String elem) {
> for(int i=0; i < list.length; i++) {
> if (list[i].toLowerCase().equals(elem)) {
> return i;
> }
> }
> return -1;
> }
> {code}
> The code assumes that every element in the list is not null, which isn't true
> because of the following code in SemanticAnalyzer.java (method genJoinTree()):
> {code}
> if ((right.getToken().getType() == HiveParser.TOK_TABREF)
> || (right.getToken().getType() == HiveParser.TOK_SUBQUERY)
> || (right.getToken().getType() == HiveParser.TOK_PTBLFUNCTION)) {
> String tableName = getUnescapedUnqualifiedTableName((ASTNode)
> right.getChild(0))
> .toLowerCase();
> String alias = extractJoinAlias(right, tableName);
> String[] rightAliases = new String[1];
> rightAliases[0] = alias;
> joinTree.setRightAliases(rightAliases);
> String[] children = joinTree.getBaseSrc();
> if (children == null) {
> children = new String[2];
> }
> children[1] = alias;
> joinTree.setBaseSrc(children);
> joinTree.setId(qb.getId());
> joinTree.getAliasToOpInfo().put(
> getModifiedAlias(qb, alias), aliasToOpInfo.get(alias));
> // remember rhs table for semijoin
> if (joinTree.getNoSemiJoin() == false) {
> joinTree.addRHSSemijoin(alias);
> }
> } else {
> {code}.
> Specifically, this code can result a null element as base source:
> {code}
> if (children == null) {
> children = new String[2];
> }
> children[1] = alias;
> {code}
> This appears to be a regression from earlier release (0.14.1). However, it's
> unclear which commit caused this.
