> With the helpful patch that Renxia posts
> https://issues.apache.org/jira/browse/NUTCH-1957, I figure out that we need
> to solve the file name collision, otherwise we will lose data. However, when
> I use this patch to execute bin/nutch dump, I get file name too long error as
> follows:
> zhangxin0804@zhangxin0804-VirtualBox:~/Desktop/Nutch/nutch/runtime/local$
> bin/nutch dump -outputDir outputDir -segment TestCrawl2/segments
> java.io.FileNotFoundException:/home/zhangxin0804/Desktop/Nutch/nutch/runtime/local/outputDir/86/fc/830433456bfbcff5f7b53661cc24d9d4_maps.php?submitted=true&year=2014&month=6&imgs%5b%5d=nationaltavgrank&imgs%5b%5d=nationaltmaxrank&imgs%5b%5d=nationaltminrank&imgs%5b%5d=nationalpcpnrank&imgs%5b%5d=regionaltavgrank&imgs%5b%5d=regionaltmaxrank&imgs%5b%5d=regionaltminrank&imgs%5b%5d=regionalpcpnrank&imgs%5b%5d=statewidetavgrank&imgs%5b%5d=statewidetmaxrank&imgs%5b%5d=statewidetminrank&imgs%5b%5d=statewidepcpnrank&imgs%5b%5d=divisionaltavgrank&imgs%5b%5d=divisionaltmaxrank&imgs%5b%5d=divisionaltminrank&imgs%5b%5d=divisionalpcpnrank&ts=3
> (File name too long)
> at java.io.FileOutputStream.open(Native Method)
> at java.io.FileOutputStream.<init>(FileOutputStream.java:221)
> at java.io.FileOutputStream.<init>(FileOutputStream.java:171)
> at org.apache.nutch.tools.FileDumper.dump(FileDumper.java:221)
> at org.apache.nutch.tools.FileDumper.main(FileDumper.java:309)
> I dig into this patch and find it only checks the length of fileBaseName in
> /nutch/trunk/src/java/org/apache/nutch/util/DumpFileUtil.java. Therefore, if
> the <extension> is too long, the final outputFullPath is still too long which
> means it will throw exception in FileDumper.java Probably not everyone will
> meet this issue and it is maybe a minor bug, correct me if I am wrong.
> Meanwhile, is that OK to truncate fileExtension name as we did on fileBase
> name to solve this problem?
