Karthik Palanisamy commented on PHOENIX-3541:
---------------------------------------------

This JIRA is inactive long. Thank [~kalyanhadoop] for your initial patch.

w/ initial patch we still face bulkload failure.  

{code}

java.lang.IllegalArgumentException: Table S."t" not found

at org.apache.phoenix.util.SchemaUtil.generateColumnInfo(SchemaUtil.java:956)
 at org.apache.phoenix.mapreduce.AbstractBulkLoadTool.buildImportColumns(AbstractBulkLoadTool.java:378)
 at org.apache.phoenix.mapreduce.AbstractBulkLoadTool.loadData(AbstractBulkLoadTool.java:211)
 at org.apache.phoenix.mapreduce.AbstractBulkLoadTool.run(AbstractBulkLoadTool.java:180)
 at org.apache.phoenix.end2end.CsvBulkLoadToolIT.testBasicImport1(CsvBulkLoadToolIT.java:467)
..

{code}

I think Apache commons-cli.version is changed to 1.4 and this incorrectly interprete QUOTES,
is caused bulkload failure. Similar one, [CLI-275|https://issues.apache.org/jira/browse/CLI-275]
\"\"t\"\"  -> ""t"" (Incorrect) 
"t"  -> t    (this is correct)
\"t\" -> t    (Incorrect)
'"t"'  -> t   (single quote - double quote - tilde - double quote - single quote =>
INcorrect)
"'"t"'" -> 't' (double - single - double - tilde - double - single - double => correct
- surprisingly to me, echo produces the same result.)
"'t'" -> 't'  (double-single-tilde-single-double) -> Correct)
'""' -> empty string (single-double-double-single) -> INcorrect)
"''" -> '' (double-single-single-double    ->   single-single   -> Correct)
"\"t\"" -> t (double - esc double - tilde - esc double - double -> INcorrect).
"\\"t\\"" -> \t\ (double - esc backslash - double - tilde - esc backslash - double ->
correct)
 

Posted new patch that handleds dual double quote from input tableName/schemaName.

\"\"t\"\"   ->  ""t""   (CLI)

""t""   -> "t" -> t (Bulkload)
