upgrade - Upgrading Cassandra -

-

My Cassandra version is 1.2.4 and I try to upgrade it to I'm 2.0.5 and I know that in the first part I have to upgrade it to 1.0.14 and then upgrade it to 2.0.5 Try

When I try to run nodetool -h localhost remondode host id then gives me this:

"main "Exception in java.lang thread. Unsupported operation exception: can not delete itself on org.apache.cassandra.service.StorageService.removeNode (StorageService.java3199) .....

Before trying that command I tried Nodetool upgradesstables

What's the problem? And how can I solve it?

OS: Ubuntu 12.04 LTS

Update

  1. Download the version 1.2.13 and the cassandra of 2.0.5 from the official site. Open Cassandra.yaml in both versions Cassandra Download
  2. Turn off the recording unit (the reading task will continue): Nodetul Dellies
  3. Stop the old Cassandra.
  4. Copy the data from current (old) Cassandra to a new version 1.2.13. Run it (1.2.13).
  5. Cassandra 1.2.13 update for the command table format: nodetool upgradesstables-a.
  6. Copy Cassandra 2.0.5 data from Cassandra 1.2.13.

    OK points

    1. Cassandra.yaml in the default virtual host - vnodes (records are included in "num_tokens: 256") in 2.0.5 In).
    2. In the 2.0.5 record, the "index_interval: 128" is functional out of the cassandra.yaml file for table-level properties.
    3. Some settings are absent from previous versions of Cassandra.yaml in 2.0.5.

python - Writing Greek in matplotlib labels, titles -

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 ...
