java - hadoop in windows with cygwin noclassdefinition found error -

-

I am trying to install Haup in my windows 7 environment and run with Sigwin. I've been Saigvin download and install and I have configured SSH, I have set the Java class path inside Saigvin Kbasrak and set all Haup configuration files. My .bashrc file listed 

  export JAVA_HOME = "C: \ \ Program Files \\ Java \\ jdk1.6.0_24" export HADOOP_HOME = / home / user / Thaup export HADOOP_MAPRED_HOME = / home HADOOP_COMMON_HOME / HADOOP_COMMON_HOME = / HOME / USER / HADOP EXPORT HADOOP_HDFS_HOME = / HOME / USER / THOVE EXPORT YARN_HOME = / HOME / USER / HADOP EXPORT HADOOP_CONF_DIR = / home / user / hasoop / etc / hasoop   
 but I could not find the error when I run the Falling command error on the Sigwin terminal:  
  $ ./hadoop version java.lang.NoClassDefFoundError: org / apache / hasoop / util / versionInfo by reason: java.lang.ClassNotFoundException: org.apache.hadoop.util.VersionInfo on Java.lang.la java. Java.security.AccessController.doPrivileged on net.URLClassLoader.findClass (URLClassLoader.java:190) java.net.URLClassLoader $ 1.run (URLClassLoader.java202) SsLoader.loadClass (ClassLoader.java:307) ) At sun.misc.Launcher $ AppClassLoader.loadClass (Launcher.java:301) java.lang.ClassLoader.loadClass (ClassLoader.java would be 48) Main category could not be found: Organization .apache.hadoop.util.VersionInfo. The program will exit thread exception "core"   
 Why do I get a noclass definition found error, Is there anything else to do with the configuration of Windows 7 64-bit and Halop version 2.2.0   
 
 
 Some Tips:  
     
  1.  Install JDK in a folder, the path should be without any white space.  
  2.  
     Set the path:  
      $ export JAVA_HOME = / cygdrive /c/Program_Files/Java/jdk1.7.0_71    
  3.  
     Ensure that the export was successful by execution:  
      $ Env | Grep-i JAVA_HOME   
     It should print:  
      JAVA_HOME = / cygdrive / c / Program_Files / Java / jdk1.7.0_71  < / Pre>  
  4.  
     If you want to see the version, just execute:  
      sh -x bin / hdfs version    sh -x :  
      sh -x bin / hdfs namedev

python - Writing Greek in matplotlib labels, titles -

Image
I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
