Jarek Jarcec Cecho updated SQOOP-1227:
--------------------------------------
Description:
The problem is in
[DataDrivenImportJob.writeAvroSchema|https://github.com/apache/sqoop/blob/trunk/src/java/org/apache/sqoop/mapreduce/DataDrivenImportJob.java#L103]
where we have following code fragment:
{code}
FileUtils.writeStringToFile(schemaFile, schema.toString(true), null);
{code}
The last parameter to the function call is {{null}} without any type. This
works fine in {{commons-io}} 1.4 as the method {{writeStringToFile}} have only
two different definitions:
{code}
writeStringToFile(File file, String data)
writeStringToFile(File file, String data, String encoding)
{code}
However later versions has added a lot of other definitions, such as:
{code}
writeStringToFile(File file, String data, Charset encoding)
{code}
And thus the compilation fails on ambiguity problem:
{code}
[javac]
/home/jarcec/apache/repos/sqoop/src/java/org/apache/sqoop/mapreduce/DataDrivenImportJob.java:109:
error: reference to writeStringToFile is ambiguous, both method
writeStringToFile(File,String,Charset) in FileUtils and method
writeStringToFile(File,String,String) in FileUtils match
[javac] FileUtils.writeStringToFile(schemaFile, schema.toString(true),
null);
[javac] ^
{code}
